Potentiometric titration of some naphthyl hydrogen sulphates and naphthyl dihydrogen phosphates
ANALYSTANALYST Pub Date: DOI: 10.1039/AN9709500552
Abstract
A rapid potentiometric titration of acid esters of naphthyl phosphates and sulphates based on acid-base properties of individual esters and their salts is described, and the values for their dissociation constants have been determined. Naphthyl dihydrogen phosphates and naphthyl hydrogen sulphates behave generally as di- and monobasic substances. Use of the proposed method, if combined with the determination of free naphthol and inorganic phosphates or sulphates, enables detailed analysis of such esters to be carried out.
