Abstract

1. The production of acidity by suspensions of stearic acid has been measured in neutral solutions of potassium chloride and potassium sulphate. 2. The variation of hydrogen-ion activity and of total acid with the salt concentration and with dilution of the suspension has been examined, and found to be consistent with the view that the observed acidity is produced by exchange of the kations of the salt with hydrogen ions formed from dissociating molecules in the surface of the insoluble acid. 3. It is considered that the production of acidity in neutral solutions of salts of strong acids in contact with an extensive surface of a weak insoluble acid is generally to be expected on the basis of accepted theory, and is capable of a simple chemical interpretation.
