摘要：

A system of ionic components of C-p,i(-0) is prposed for the standard partial molar heat capacities C-p2(-0) of electrolytes in a mixed N-methylpyrrolidone (MP)-water solvent. The C-Pi(-0), values are calculated for Li+, Na+, K+, Rb+, Cs+, and I- ions in a mixed MP-water solvent at 298.15 K. The individual components of C-p,i(-0) values and their dependence on the solvent composition and ion size are considered.
