PREFACE TO FIRST EDITION 

FOR many years a need has been felt by chemists for a book which shall collect 
into convenient form for ready reference the various data concerning the solu- 
bility of chemical substances that have been published from time to time nx 
chemical periodicals and elsewhere 

The first mention that can be found of such a plan was made in 1731, when 
Peter Shaw delivered Chemical Lectures in London, as may be seen from the 
following 

EXTRACTS from PETER SHAW'S Chemical Lectures, pubhckly read at London in 
1731 and 1732 London Second Edition, London 1755 8vo 

Page 97 Experiment I That Water as a Menstruum dissolves more of one body 
and less of another 

[He shows that two ounces of water dissolve two ounces of Epsom salt, five drachms of 
common salt ? and eight grains of cream of tartar Only in the latter case much remained 
undissolved until boiled ] 

"It might be proper for the further Improvement of Chemistry and Natural Phi- 
losophy to form a Table of the Time and Quantity wherein all the known Salts are 
dissolvable in Water Such a Table regularly formed might ease the Trouble of re- 

fining Salts, by shewing at once without future Trial or Loss of Time how much Water 
each Salt required to dissolve it for Clarification, Filtration, or Crystallization It would 
likewise supply us with a ready and commodious Wav of separating any Mixture of Salts, 
by shewing which would first shoot out of the Mixture upon Crystallization The 

same Table might also direct us to a ready and commodious Method of separating two 
Salts without waiting for Crystallization " 

It was many years, however, before the scheme suggested by Peter Shaw 
was put into execution Professor F H Storer published the first work that 
undertook to carry out the idea in its entirety, in 1864, m a book, which he 
entitled " First Outlines of a Dictionary of Solubilities of Chemical Substances," 
and which contained a compilation of nearly all the data on the subject pub- 
lished before 1860 It was at once recognized as a most valuable contribution 
to chemical literature, but for many years it has been difficult to obtain this 
work, as the limited edition which was published was soon wholly exhausted 
Since then nothing has appeared on the subject except the brief tabulations 
found in various reference books, and no attempt has been made to cover the 
whole subject 

It is needless to state that the growth of chemical science since the publication 
of Professor Storer's book has been so enormous that that work has lost, at least 
to a great extent, the practical value it possessed thirty years ago This growth 
has been indeed so great, and the data which have accumulated since 1860 so far 
surpass the earlier in volume, that a simple revision of Professor Storer's book 
was impracticable, and it therefore seemed best to start afresh 



vi PREFACE TO FIRST EDITION 

With the facilities offered by the various scientific libraries at Harvard 
University, the Massachusetts Institute of Technology, and other libraries in 
Boston, it has been possible to collect nearly all the data relating to the subject 
For the work before 1860 Professor Storer's work has been found invaluable 

The method pursued has been to form a preliminary list of compounds 
with more or less data by consulting the two most complete works on inorganic 
chemistry Gmehn-Kraut's "Handbuch der anorgamschen Chemie" and 
Graham-Otto-Michaehs's "Lehrbuch " These statements have been verified 
and elaborated by consulting the original memoirs in all the periodicals devoted 
to chemical literature which were obtainable The " Jahresbencht der Chemie " 
also has been used extensively in tracing references, but the original memoirs 
have always been consulted and references given to them when possible 

It has been found impracticable to draw any distinction as to reliability 
between the various data given by different observers It was manifestly 
impossible to attempt to verify experimentally the statements of those who 
have earned on the researches, for the most assiduous labor of many could 
only cover a small portion of the attested facts Therefore, even when two 
statements are directly contradictory, both have been given with thfc authority 
for each The only exception to this has been made when more recent dis- 
coveries have shown beyond any reasonable doubt the falsity of previous work 
In this way some of the older manifestly inaccurate work has been omitted In 
a majority of cases the more recent work may be considered to be the more 
accurate, but this is not the invariable rule A Synchronistic Table of the more 
common periodicals is given in the Appendix, whereby it is easy to determine 
the date of the publication of a research to which reference is made 

It may be objected by the practical chemist that most of the woik previous 
to 1850 might well have boon omitted, but a groat deal of this woi k posse sscs at 
least a historical value, and often furnishes facts which have not since bun 
verified Much of the earlier work when obviously of 1< ss irnportam < , h is bee n 
printed m smallei type 

The aim has been to include in this volume all analyze el moig IUK substaiie es, 
that is, all substances which do not e on tain e arbon, but e xe e. ptiem h is bee n in tele 
in the case of CC>2 7 CO, C$2, the eaibonites, eyanules, feiro-ey imde s, e te , 
which are here, mcludeel 

The work has been bi ought up to March, 1894, when this volume went 1o 
press, and the results of rt scare hts pubhsheel since that time are not melueleel 
in the present edition 

It is hoped that this book will fill to some extent the wint that has been felt 
by chemists for a compilation of this nature While it has be en attempted to 
make the book as free from errors as possible, nevertheless it is natuially im- 
possible to avoid many mistakes, and the compiler will be very grateful to those 
who may call his attention to any errors or omissions

PREFACE TO SECOND EDITION 

DTIRING the twenty-five years which have elapsed since the publication of the 
first edition of this dictionary, a very large amount of work has been published 
in chemical periodicals, containing data concerning the solubility of inorganic 
chemical compounds As it was impossible for the compiler of the first edition 
to devote the time necessary for the collecting of the published data, it was 
necessary to employ assistance, and Dr Dorothy A Hahn, Professor of Chem- 
istry, Mt Holyoke College, was engaged for this work Dr Hahn has collected 
the larger part of the material in this book, which work in spite of its arduous 
and tedious nature, she has performed in a most painstaking manner 

The compilation and arrangement of the data collected by Dr Hahn, which 
devolved upon the original author, took much time This, together with diffi- 
culties in printing, caused by the general conditions after the war, has delayed 
the publication until the present year, although the work was begun in 1916, 
and it has only been brought up to January 1st of that year 

Since the publication of the first edition of this work, Dr Atherton Seidell has 
brought out two editions of his book, entitled " Solubilities of Inorganic and 
Organic Substances," which covers quite a different field, as he considers only 
quantitative data and those only for the commoner substances Dr Seidell has 
followed the plan m most cases where there are several available solubility 
determinations of a substance, of selecting and averaging the more reliable 
results, and embodying them m tables Although this undoubtedly facilitates 
ready reference, it has seemed better to adhere to the original plan of the first 
edition, and to publish all the data m the form of the original authorities with 
references and dates, so that the user may be at liberty to use his own judgment 
m selection Some few of the tables arranged by Di Seidell, however, have 
seemed to possess decided advantages over any other published data and they 
have been me orpoiated m the present volume It is desired also to acknowledge 
indebtedness to Dr Seidell's work for ceitam other tables where the original 
souices were not available to the piesent compilers 

The same plan and airangement used m the fiist edition has been followed 
with ceitam elaboration, however, of the anangement of data on the solubility 
of two or more salts in a solvent, which is explained m the Explanatory Pieface 

Data published since the first edition on the cobalt and chi omium ammonia 
compounds and those of the platinum group have been omitted, as it seemed 
that solubility data on those compounds possessed very little general interest 

As stated m the preface of the first edition, while every possible attempt has 
been made to avoid errors, it is manifestly impossible to avoid many mistakes m 
a work of this nature, and the compiler will be glad to have his attention called 
to any errors or omissions

EXPLANATORY PREFACE 

IN order to reduce this volume to a convenient size the subject-matter has been 
abbreviated and condensed as far as seemed compatible with clearness, but it 
has been the aim not to use any abbreviations which are not at once intelligible 
without consulting the explanatory table The more common chemical for- 
mulae have been universally used, thereby saving a large amount of space 
without detracting from ready intelligibility to chemists 

The solubility of the substance in water is first given, the data being arranged 
chronologically in the longer articles Then follow the specific gravities of the 
aqueous solutions, and also any data obtainable regarding their boiling-points, 
other physical data concerning solutions are not included Following this is the 
solubility of the substance in other solvents first the inorganic acids, then 
alkali and salt solutions, and finally organic substances 

Owing to the great increase of data, published during the last twenty years, 
on the simultaneous solubility of two or more salts in a given solvent, it has 
been found necessary to plan some arrangement, whereby such data can easily 
be found, and the plan adopted is as follows The data for the solubility of two 
salts in a solvent is placed under the salt which comes first according to the 
alphabetical arrangement in this dictionary, and the order of the data on various 
salts under the same heading follows the alphabetical order of the salts consid- 
ered Thus the data on the solubility of NH 4 Cl+BaCl 2 , NH 4 Cl+CuCl 2 , 
and NH 4 Cl+PbCl2, and NEUCl+CNEU^SCU are placed under Ammonium 
Chloride and arranged in the given order Certain exceptions have been made 
to this rule, where the data directly concerns the solubility of a salt in a solu- 
tion of another salt, in which case, it is placed undei the former Numerous 
cross references, however, are given, which it is hoped will avoid confusion 

In many cases no definite distinction can be drawn between the phenomena 
of solution and decomposition \t present the theory of solution is in a confused 
state, and until what really takes place when a substance dissolves is thoroughly 
understood no distinct line can be drawn The whole subject is unsettled at the 
present time, foi while many chemists believe m the so-called " dissociation" 
theory, yet the "hydrate" theory is not without its supporters It is not my 
intention to discuss the theoretical side of the question, which has been so well 
treated in many recent works It is, however, obvious that the phenomena are 
essentially different, when, for example, sodium carbonate is dissolved in water, 
m which case the original salt is deposited on evaporation, and when iron is 
dissolved m sulphuric acid, and the solution deposits a sulphate of iron Yet it 
is still the custom to speak of iron as soluble in sulphuric acid, although it would 
be much more accurate to say that the sulphuric acid was decomposed by the 
iron It has thus been found impracticable to draw a sharp line between solu- 



EXPLANATORY PREFACE 



tion and decomposition, and the term " soluble " has in general been usec 
where a solution of some sort is formed by the action of the solvent 

The matter of alphabetical arrangement of chemical compounds, in th 
present somewhat confused state of chemical nomenclature, has been a difficuli 
question to decide The plan followed has been practically that of the standarc 
Dictionaries of Chemistry, whereby the compounds of metals with one of the 
non-metallic elements have been classified under the metals, while the salts oJ 
the other acids (the oxygen acids so called and some few others) have beer 
arranged alphabetically under the acids Thus barium chloride is found undei 
barium, while barium chlorate is found under chloric acid No exception ha c 
been made in the case of the rare metals, as is usually the custom in Dictionarie c 
of Chemistry Double salts are to be found under the word which comes first 
alphabetically, thus, "common alum," potassium aluminum sulphate, is found 
under aluminum sulphate as aluminum potassium sulphate (under sulphunc 
acid), but ammonia, chrome alum is found under ammonium sulphate as am 
momum chromium sulphate In the same way the double sulphate and chro 
mate of potassium is found under potassium chromate (chromic acid), and not 
under potassium sulphate (sulphuric acid) The double chloride of ammonium 
and magnesium is found under ammonium chloride (ammonium), while the 
double chloride of potassium and magnesium is found under magnesium chloride 
(magnesium) An exception is made, however, m the case of double compound* 
of salts of oxygen acids with salts containing a bingle non-metallic element, 111 
which case they are always found under the oxygen acid Thus the double 
sulphate and chlonde of lead, PbSO^ PbClo, ib found uud( i k id sulphate 
(sulphunc acid), and not undei kad chlonck (lead) 

The above method m some casts widdy sepuates antlogous compounds

taming one of the metals For example, "fluosihcates" (or sihcofluondes, as 
some may prefer) is the general name for the double fluorides of SiF 4 and a 
metal, but this unanimity in usage gradually disappears as the basic elements 
become more nearly alike, so that it is impossible to draw a line between such 
compounds and a compound such as the double chloride of magnesium and 
potassium, for which indeed the name " potassium chloromagnesate" has been 
proposed The aim has been in all these cases to follow the best usage rather 
than make an absolutely homogeneous system of nomenclature out of the exist- 
ing confusion 

In the matter of formulae no attempt at uniformity has been made Thus in 
the case above some chemists wnte the formula of the double chloride of mag- 
nesium and potassium as KMg,Cl 3 , others as KC1, MgCl 3 The form here 
used has been in most cases that of the author from whom the data are taken 

The prefixes mono, di, tn, ortho, pyro, etc , have in general been disregarded 
in the alphabetical arrangement, and have been printed in italics Exceptions 
to this have been made, however, in the cobalt, chromium, etc , ammonium 
compounds, and m a few others, as dithionic, perchloric, etc , acids Cross 
references have been used, so as to prevent any confusion arising from lack of 
uniformity in this respect 

In the Appendix will be found formulae and tables for the conversion of the 
degrees of various hydrometer scales into specific gravity, and a Synchronistic 
Table of the Periodicals to which references aie most fiequenth made

Herz (Z anorg 25 155) found that alum- 
lum hydroxide which has been dried in a 
acuum dessicator requires f or solution in 
faOH+Aq 3 atoms Na to 1 atom Al 
lade (Z Mektrochem 1911, 17 261) *as 
nable to obtain this result Her/ says Slade's 
rror is due to insufficient shaking of the solu- 
on (Herz Z Elektrochem 1911, 17 403 ) 

New solubility determinations verify the 
batement of Herz (Z anorg 25, 155) that the 
Dlubihty of A1(OH) 3 in NaOH-f Aq is pro- 
ortional to the concentration of NaOH 
hey do not, however, veiify his statement 
hat the ratio Na Al in the solutions is al- 
ways 3 1, for the author finds that the ratio

Solubility in H 2 is inci eased by presence 
of KC1, KN0 3 , K 2 S0 4 , NaN0 3 and Na 2 SO 4 

In general the solubility in H 2 O is increased

Solubility of CaO m KC1 and NaCi+Aq 
Curves arc given which show that the solu- 
bility of lime m solutions of either NaCl or 



KC1 is a maximum for all 


temps when the 


solution contains about 60 


ff of salt per 1 


It is a minimum at any fixed temp when the 
solution is sat , the solubility then being 


much less than in pure H 2 O of the same temp 


A solution of NaCl dissolves more lime at all 


temps and concentrations than a correspond- 
ing solution of KC1 In all cases the maximum 


solubility of lime occurs when the temp is 


lowest With solutions of all concentrations 


the solubility decreases regularly as the temp 


increases (Cabot, J Soc Chem Ind 1897, 


16 417-419) 








Solubility in KCl+Aq increases with in- 


creased quantities 


of KC1 


and then dunin- 


ishes, becoming le

C0 2 is not disengaged at ordinary temp 
from H 2 O, m which Viroo pt of CaC0 3 or 
MgC0 8 is held in solution thereby These 
solutions have a great power of retaining C0 2 
even at a boiling temp or with diminished 
pressure, and they also absorb CO 2 from the 
air in much larger quantity than pure H 2 
(Bmeau ) 

BaCOa in H 2 also retains C0 2 even after 
long boiling (Storer )

NH 4 OH+Aq wholly sat with C0 2 pro-

Also when an excess of CaCl 2 +Aq is added to

In a solution near the saturation point and 
m equihbnum with atmospheric air upwards 
of 50 per cent of the magnesium is in the 
form of the normal carbonate When the 
solution is brought m contact with the solid 
phase, the proportion of the base combined 
as normal carbonate falls to about 34 per 
cent, or lower (Cameron and Bnggs, J

For solubility in H 2 CO 8 -f Aq, see Magne-

Scarcely acted upon by HCl+Aq (Senar-

(Roscoe and Dittmar ) 



(Roscoe and Dittmar ) 

Cone HCl+Aq gradually gives off HCl on 
the air until it has a sp gr 1 128 at 15, and 
contains 25 2% HCl (Bineau, I c ) 

According to Roscoe and Dittmar, this de- 
pends on the temperature If a current of an 
[s passed through HCl+Aq, acid or water 
is given off according as the acid is strong 01 
weak, until an acid of constant composition 
for a given temperature is formed, as follows

From the above it is seen that the acid 
which distils unchanged at a given pressure, 
that is, boils at a certain constant tempera- 
ture, is identical \vith the acid which under- 
goes no change in composition by a current 
of dry air at the same tempeiature, and undei 
the ordinary pressure, thus

of which are AgCl, Hg 2 CU, Cu 2 Cl 2 , PtCl 2 , and 
AuCl Several chlorides are decomp into 
insol basic salts or hydroxides, either by the 
addition of H 2 O, as in the case of BiCl 3 and
