Osmotic and activity coefficients of nonaqueous electrolyte solutions. 1. Lithium perchlorate in the protic solvents methanol, ethanol, and 2-propanol

摘要

Vapor pressure lowering by the addition of LiClO4 to the protic solvents methanol (0.04-5.1 m), ethanol (0.03-1.5 m), and 2-propanol (0.05-1.5 m) was measured at 25 degrees C with high precision. The experimental data of the corresponding osmotic coefficients are compared to those obtained by the use of Fitter equations and chemical model calculations. Mean activity coefficients are derived from the osmotic coefficients. [References: 23]
