Effect of Potassium Halides on the Equilibrium of Aqueous T-Butanol System at 30°C-II

Ultrasonic velocity and density have been measured experimentally at 30°C in t-butanol+water system at low concentrations. To this aqueous t-butanol system, small quantities of potassium halides, KCl, KBr and KI have been added and the measurements repeated. From the velocity peaks and compressibility minima, the effect of potassium halides on the clathrate structures of aqueous t-butanol system has been studied. Also by computing apparent molar volumes and apparent molar compressibilities, ion-solvent, solute-solvent interactions are estimated in the total system.
