Abstract

R. S. Lokhande and P. U. Singare

A known amount of ion exchange resin in chloride form was equilibnated with iodide ion solution of five different concentrations from 0.009 M to 0.037 M. at different temperatures ranging from 30.0°C to 45.0°C. Mole traction of iodide ions (N.-) and chloride ions (NCI) in the resin phase were calculated from which equilibrium constant (K') was calculated using Bonner et.ai equation. From the Knowledge of equilibrium constants at different temperatures, enthalpy of ion exchange reaction was obtained to be 19.1 KJoules/mole.
