This volume presents solubility data of azides, cyanides, cyanates, and thiocyanates ofalkali metals, alkaline earth metals, and ammonium. Covered are binary and ternarysystems in all solvents. No solubility data have been found for some of the compounds ofalkali metals, alkaline metals, and ammonium. These include beryllium and magnesiumazides, lithium, rubidium cesium, ammonium, and alkaline earth cyanates and cyanides,and beryllium thiocyanate. Likewise, no solubility data seem to exist for selenocyanatesof the mentioned metals and ammonium. The literature has been covered up to the middleof 2001, and there was a great effort to have the literature survey as complete as possible.The few documents which remained unavailable to the editor, and could not be includedin the volume, are listed in the Appendix. For some compounds it was not possible toshow theChemical Abstractsregistry numbers since these have not been assigned. Forthis reason, the registry number index is incomplete. ©2004 American Institute ofPhysics. @DOI: 10.1063/1.1563591#

1. Preface
This volume presents solubility data of azides, cyanidcyanates, and thiocyanates of alkali metals, alkaline emetals, and ammonium. Covered are binary and ternarytems in all solvents. No solubility data have been foundsome of the compounds of alkali metals, alkaline metals,ammonium. These include beryllium and magnesium azidlithium, rubidium cesium, ammonium, and alkaline earth canates and cyanides, and beryllium thiocyanate. Likewisesolubility data seem to exist for selenocyanates of the mtioned metals and ammonium. The literature has been cered up to the middle of 2001, and there was a great effohave the literature survey as complete as possible. Thedocuments which remained unavailable to the compiler,could not be included in the volume are listed in the Appedix. For some compounds it was not possible to showChemical Abstractsregistry numbers since these have nbeen assigned. For this reason, the registry number indeincomplete.
In addition to documents that published numerical dasome papers that presented data in graphical form only wincluded as well. They were considered for the volume eitif no other data were available for the system, or if the dwere published in difficult to obtain older literature. Thecriteria led the compiler to include sometimes paperswhich the authors failed to specify conditions such as teperature, equilibrium time, or methods of analysis. Phdiagrams have been included for some of the ternarytems. For binary eutonic systems, phase diagrams werecluded only if no numerical data were reported in the orinal documents and the diagrams were the sole sourcinformation. Of the many systems covered by the volumrelatively few were studied by more than one laboratoThus the opportunity to carry out evaluations has been lited, and only 20 systems have been evaluated. Howebecause of some uncertainty in most of the evaluatedtems, only tentative solubility values could usually be reommended.
Only those published results that report meaningful dwere considered for the volume. Papers that reported qutative results with statements like ‘‘sparingly soluble’’ or ‘‘insoluble,’’ etc., were not considered. However, some doments reported solubility data which, although not includin the volume for one reason or other~e.g., single values ouncertain quality without any supporting informatiosketches of phase diagrams!, may nevertheless be of sominformative value to the potential user of this volume in cathey represent the only information available for a given stem. For this reason, a list of systems for which only sudata exist has been included in the Appendix.

2. Introduction to the Solubility Data Series:Solubility of Solids in Liquids
2.1. The Nature of the Project
The Solubility Data project~SDP! has as its aim a comprehensive review of published data for solubilities of gasliquids, and solids in liquids or solids. Data of suitable prcision are compiled for each publication on data sheetsuniform format. The data for each system are evaluated awhere data from independent sources agree sufficiently,ommended values are proposed. The evaluation sheets,ommended values, and compiled data sheets are publion consecutive pages.
2.2. Compilations and Evaluations
The formats for the compilations and critical evaluatiohave been standardized for all volumes. A descriptionthese formats follows.
2.2.1. Compilations
The format used for the compilations is, for the most paself-explanatory. Normally, a compilation sheet is dividinto boxes, with detailed contents described below.
Components
Each component is listed according to IUPAC name, fmula, and Chemical Abstracts~CA! Registry Number. TheChemical Abstracts name is also included if this differs frothe IUPAC name, as are trivial names if appropriate. IUPAand common names are cross-referenced to Chemicalstracts names in the System Index.
The formula is given either in terms of the IUPAC or Hil1
system and the choice of formula is governed by whausual for most current users: i.e., IUPAC for inorganic copounds, and Hill system for organic compounds. Comnents are ordered on a given compilation sheet according
~a! saturating components;~b! non-saturating components;~c! solvents.In each of~a!, ~b! or ~c!, the components are arranged
order according to the IUPAC 18-column periodic table wtwo additional rows:
Columns 1 and 2: H, alkali elements, ammonium, alkalearth elements
Columns 3 to 12: transition elementsColumns 13 to 17: boron, carbon, nitrogen groups; ch
cogenides, halogensColumn 18: noble gasesRow 1: Ce to Lu

Original Measurements
References are abbreviated in the forms given by Checal Abstracts Service Source Index~CASSI!. Names origi-nally in other than Roman alphabets are given as translated by Chemical Abstracts. In the case of multiple entr~for example, translations! an asterisk indicates the publication used for compilation of the data.
Variables
Ranges of temperature, pressure, etc., are indicated h

The names of all compilers are given here.
Experimental Data
Components are described as~1!, ~2!, etc., as defined inthe ‘‘Components’’ box. Data are reported in the units usin the original publication, with the exception that modenames for units and quantities are used; e.g., mass pefor weight percent; mol dm23 for molar; etc. Usually, onlyone type of value~e.g., mass percent! is found in the originalpaper, and the compiler has added the other type of v~e.g., mole percent! from computer calculations based o1989 atomic weights.2 Temperatures are expressed ast/°C,t/°F or T/K as in the original; if necessary, conversionsT/K are made, sometimes in the compilations and alwaythe critical evaluation. However, the author’s units arepressed according to IUPAC recommendations3 as far as pos-sible.
Errors in calculations, fitting equations, etc., are noted,where possible corrected. Material inserted by the compis identified by the word ‘‘compiler’’ or by the compiler’sname in parentheses or in a footnote. In addition, compicalculated values of mole or mass fractions are includethe original data do not use these units. If densities areported in the original paper, conversions from concentratito mole fractions are included, but otherwise this is donethe evaluation, with the values and sources of the densbeing quoted and referenced.
Details of smoothing equations~with limits! are includedif they are present in the original publication and if the teperature or pressure ranges are wide enough to justifyprocedure and if the compiler finds that the equationsconsistent with the data.
The precision of the original data is preserved whenrived quantities are calculated, if necessary by the inclusof one additional significant figure. In some cases, compinote that numerical data have been obtained from publisgraphs using digitizing techniques. In these cases, the psion of the data can be determined by the quality of

Method
The apparatus and procedure are mentioned briefly. Abviations used in Chemical Abstracts are often used heresave space, reference being made to sources of further dif these are cited in the original paper.
Source and Purity of Materials
For each component, referred to as~1!, ~2!, etc., the fol-lowing information~in this order and in abbreviated form! isprovided if available in the original paper: source and spefied method of preparation; properties; degree of purity.
Estimated Error
If estimated errors were omitted by the original authoand if relevant information is available, the compilers haattempted to estimate errors~identified by ‘‘compiler’’ or thecompiler’s name in parentheses or in a footnote! from theinternal consistency of data and type of apparatus usMethods used by the compilers for estimating and reporterrors are based on Ku and Eisenhart.4
Comments and Õor Additional Data
Many compilations include this section which providshort comments relevant to the general nature of the woradditional experimental and thermodynamic data whichjudged by the compiler to be of value to the reader.
References
The format for these follows the format for the OriginMeasurements box, except that final page numbers are oted. References~usually cited in the original paper! are givenwhere relevant to interpretation of the compile data, or whcross-reference can be made to other compilations.
2.2.2. Evaluations
The evaluator’s task is to assess the reliability and quaof the data, to estimate errors where necessary, and toommend ‘‘best’’ values. The evaluation takes the form osummary in which all the data supplied by the compiler habeen critically reviewed. There are only three boxes ontypical evaluation sheet, and these are described below.

Evaluator
The name and affiliation of the evaluator~s! and date up towhich the literature was checked.
Critical Evaluation
~a! Critical text. The evaluator checks that the compildata are correct, assesses their reliability and quality, emates errors where necessary, and recommends numevalues based on all the published data~including theses, patents and reports! for each given system. Thus, the evaluareviews the merits or shortcomings of the various data. Opublished data are considered. Documented rejectionsome published data may occur at this stage, and the csponding compilations may be removed.
The solubility of comparatively few systems is knowwith sufficient accuracy to enable a set of recommendedues to be presented. Although many systems have beenied by at least two workers, the range of temperatureoften sufficiently different to make meaningful comparisimpossible.
Occasionally, it is not clear why two groups of workeobtained very different but internally consistent sets ofsults at the same temperature, although both sets of rewere obtained by reliable methods. In such cases, a definassessment may not be possible. In some cases, two orsets of data have been classified as tentative even thougsets are mutually inconsistent.
~b! Fitting equations. If the use of a smoothing equationjustifiable the evaluator may provide an equation represing the solubility as a function of the variables reportedall the compilation sheets, stating the limits within whichshould be used.
~c! Graphical summary. In addition to~b! above, graphicalsummaries are often given.
~d! Recommended values. Data are recommended if thesults of at least two independent groups are availablethey are in good agreement, and if the evaluator has no das to the adequacy and reliability of the applied experimeand computational procedures. Data are reported as tentif only one set of measurements is available, or if the evaator considers some aspect of the computational or expmental method as mildly undesirable but estimates thashould cause only minor error. Data are considered as doful if the evaluator considers some aspect of the comptional or experimental method as undesirable but still coners the data to have some value where the order of magnof the solubility is needed. Data determined by an inadequmethod or under ill-defined conditions are rejected. Hoever, references to these data are included in the evaluatogether with a comment by the evaluator as to the reasontheir rejection.
~e! References. All pertinent references are given here,cluding all those publications appearing in the accompanycompilation sheets and those which, by virtue of their poprecision, have been rejected and not compiled.

2.3. Quantities and Units Used in Compilation andEvaluation of Solubility Data
2.3.1. Mixtures, Solutions and Solubilities
A mixture5 describes a gaseous, liquid or solid phase ctaining more than one substance, where the substances atreated in the same way.
A solution5 describes a liquid or solid phase containinmore than one substance, when for convenience one osubstances, which is called thesolvent, and may itself be amixture, is treated differently than the other substancwhich are calledsolutes. If the sum of the mole fractions othe solutes is small compared to unity, the solution is cala dilute solution.
The solubility of a solute 1~solid, liquid or gas! is theanalytical composition of a saturated solution, expressedterms of the proportion of the designated solute in a denated solvent.6
‘‘Saturated’’ implies equilibrium with respect to the processes of dissolution and precipitation; the equilibrium mbe stable or metastable. The solubility of a substancemetastable equilibrium is usually greater than that ofsame substance in stable equilibrium.~Strictly speaking, it isthe activity of the substance in metastable equilibrium thagreater.! Care must be taken to distinguish true metastabifrom supersaturation, where equilibrium does not exist.
Either point of view, mixture or solution, may be takendescribing solubility. The two points of view find their expression in the reference states used for definition of acties, activity coefficients and osmotic coefficients.
Note that the composition of a saturated mixture~or solu-tion! can be described in terms of any suitable set of thermdynamic components. Thus, the solubility of a salt hydratewater is usually given as the relative proportions of anhdrous salt in solution, rather then the relative proportionshydrated salt and water.
2.3.2. Physicochemical Quantities and Units
Solubilities of solids have been the subject of researcha long time, and have been expressed in a great many was described below. In each case, specification of the tperature and either partial or total pressure of the saturagaseous component is necessary. The nomenclature andfollow, where possible, IUPAC Green Book.3 A few quanti-ties follow the ISO standards7 or the German standard;8 see areview by Cvitasˇ9 for details.
A Note on Nomenclature
The nomenclature of the IUPACGreen Book3 calls thesolute component B and the solvent component A. In copilations and evaluations, the first-named component~com-

Salt hydrates are generally not considered to be saturacomponents since most solubilities are expressed in termthe anhydrous salt. The existence of hydrates or solvatenoted carefully in the critical evaluation.
Mineralogical names are also quoted, along with theirRegistry Numbers, again usually in the text and CA RegisNumbers~where available! are given usually in the criticaevaluation.

For liquidsolutions, the reference substance is often water at 4 °~C!, 1bar. ~In some cases 1 atm is used instead of 1 bar.! The termspecific gravityis no longer used.
Thermodynamics of Solubility
Thermodynamic analysis of solubility phenomena pvides a rational basis for the construction of functionsrepresent solubility data, and thus aids in evaluation,sometimes enables thermodynamic quantities to be extraBoth these aims are often difficult to achieve because olack of experimental or theoretical activity coefficientWhere thermodynamic quantities can be found, they areevaluated critically, since this task would involve examintion of a large body of data that is not directly relevantsolubility.
