A novel potentiometricsensor for simple, sensitive, and selective determination of acetate ion is developed and electrochemically evaluated. This assembly is based on the use of a flat-bottom combination glass pH electrode behind a Teflon membrane and in contact with a thin film of sodium acetate-sodium chloride internal electrolyte solution. Acidifying the analyte acetate solution to pH
