Low solubility coefficient
WebGraphically it was observed that solubility in pH buffer solutions in acidic medium was slightly higher than basic pH. The partition coefficient of benzoic acid in benzene-water system was found to be 0.636 and in buffer solutions of pH 4.0, pH 7.0 and pH 9.0 were 0.841, 0.624 and 0.589 respectively.
