Temperature Variation of Accustic Velocity in Aqueous Solutions of Electrolytes

Abstract

Temperature variation of ultrasonic velocity in aqueous solutions of chlorides of magnesium, strontium, and barium, bromides of strontium and barium and oxalates of lithium and potassium has been studied using the fixed-path interferometer technique. Variation of adiabatic compressibility, molar sound velocity, apparant molal compressibility and hydration number, with temperature has also been studied and the results are discussed in the light of the Marks’ finding in a similar study of the electrolytes.
