IUPAC-NIST Solubility Data Series. 89. Alkali Metal Nitrates. Part 1. Lithium Nitrate

This paper is the first part in the nitrate solubility volume. The solubility data for lithium nitrate are reviewed. Where appropriate, binary, ternary, and multicomponent systems are critically evaluated. Most of the solubility results were obtained in water or aqueous solutions. The solubility in ethanol and in alcohol+water solvent mixtures is also included. All data were critically examined for their reliability. The best values were selected on the basis of critical evaluations and presented in tabular form. Fitting equations and plots are also provided. The quantities, units, and symbols used are in accord with IUPAC recommendations. The original data have been reported and, if necessary, transferred into the units and symbols recommended by IUPAC. The literature on solubility data was researched through 2007.

IUPAC - NIST Solubility Data Series 66. Ammonium Phosphates

The solubility of ammonium phosphate is reviewed. Many ammonium phosphates can be described in terms of the ternary system: NH3–PO5–H2O. However, this system differs from systems like the sulfates and halates in that it has a marked tendency to form condensed oligophosphate ions. The literature survey covers the period up to 1988.

IUPAC-NIST Solubility Data Series. 93. Potassium Sulfate in Water

The solubility data for potassium sulfate in water are reviewed. All data were critically examined for their reliability. The best values were selected on the basis of critical evaluations and presented in tabular form. Fitting equations and plots are also provided. The quantities, units, and symbols used are in accord with IUPAC recommendations. The original data have been reported and, if necessary, transferred into the units and symbols recommended by IUPAC. The literature on solubility data was researched through 2010.

The influence of the degree of organization of saturated solutions on the shape of the solubility isotherm

Abstract Special features of solubility isotherms of salt hydrates have been observed, from which the evidence of strong organization of saturated solutions of hydrates may be deduced. Often observed low contents of the non saturating component in the eutonic solution limiting the crystallization branch of hydrated salts is put into connection with this result. The composition of the respective eutonic solutions exhibits a correlation with the hydration entropy of the ions present in the ternary saturated solution.

A Study of Ammonium Mono-, Di- and Triphosphate Heterogeneous Systems in View of their Use as Liquid Fertilizers

Abstract Ammonium phosphates belong among principal compounds of multicomponent liquid fertilizers and thus this study has been directed toward agrochemical application. For this reason, in the system of NH+ 4, H+ PO3 4, P2O4 7, P3O5- 10 - H2O, the subsystem, NH4H2PO4 - (NH4)2H2P2O7 - (NH4)3H2P3O10[sbnd](NH4)3PO4 - (NH4)4P2O7 - (NH4)5P3O10 - H2O, was studied in which the pH of saturated solutions varies from 5 to 8. The solubility was studied in the partial pseudoternary systems. The experimental temperatures were selected immediately above the corresponding cryohydratic points, from 0 to -8°C. The sum of the results obtained can be schematically represented as a set of the curves of simultaneous crystallization of two solids on the mantle of a trigonal prism which represents the salt composition of the studied system.
