First heats of solution δH0 of salts in nonaqueous and mixed solvents

A theoretical method is considered for determining H₀ for dissolution of salts in nonaqueous and mixed solvents at various temperatures using published and experimental data for H_m, Values of H₀ were calculated for the dissolution of salts in a number of nonaqueous and mixed solvents at various temperatures. The results obtained were compared with the published data.With an isothermal microcalorimeter, H_m values were determined for the dissolution of potassium nitrate at 25 C in water-glycerol mixtures of various compositions. The results are explained in relation to the structural characteristics of the solvent.
