The E-pH curve is linear with slope of 0.0501 V/dec at 298 K which is close to the theoretical value 2.303 RT/F (0.059 V at 298 K). The standard potential of this electrode, E0, is computed as 722.9 mV with respect to saturated calomel electrode as reference electrode. The recovery percentages for potentiometric titration are calculated. The prepared modified electrode was used in potentiometric titrations for CH3COOH against NaOH as titrant in aqueous medium at 298 K. Keywords Potentiometric titration; Solid state pH electrode
