Abstract
The heat capacities and densities of three-component solutions NaI–CdI2–N-methylpyrrolidone (NMP), KI–CdI2–NMP, RbI–CdI2–NMP, ВаI2–CdI2–NMP, NaNO3–Cd(NO3)2–NMP at 298.15 K are investigated via calorimetry and densimetry. The values of the heat capacities and volumes upon the formation of three-component systems from binary solutions are calculated and discussed. It was established for all of the investigated systems that their deviations from additivity are due to the predominance of processes of acido complex formation.
