electrolytic solutions

Ultrasonic absorption and velocity measurements have been used by several workers in the study of molecular interactions in liquids, polymers, liquid mixtures and electrolyte solutions. In this paper, a number of acoustic parameters have been evaluated for three pure liquids and their two binary mixtures, as functions of temperature and concentration. Excess values (experimental-ideal) have also been evaluated for some parameters in the case of the mixtures. The significance of these parameters and their mathematical expressions are given in the literature. The calculations are based on the ultrasonic velocity data obtained experimentally by Subrahmanyam et al.
