Abstract
A method for calculating the acidity level of mixtures of concentrated acidic solutions is presented. The method is based on the concept of isoacidity and the Zdanovskii rule. The calculated acidity function Ro(H) for ternary mixtures of phosphoric, sulfuric and perchloric acid are in good agreement with the values determined experimentally by electrochemical measurements.
