Abstract

This report documents the evaluation results of POSAI-316 electrode used as an alternative to conventional glass-indicator electrode to measure pH in ampiciline's potentiometric micro-titration. The results obtained showed a complete equivalency of POSAI-316 to conventional glass electrode during the titration of ampiciline (in CH3COOH ) with HClO4. [ABSTRACT FROM AUTHOR]

Abstract

This report documents the evaluation results of POSAI-316 electrode used as an alternative to conventional glass-indicator electrode to measure pH in caffeine's potentiometric micro-titration. The results obtained showed a complete equivalency of POSAI-316 to conventional glass electrode during the titration of caffeine (30, 40 y 50 mg in CH3COOH) with HClO4. [ABSTRACT FROM AUTHOR]
