Development of a Novel Solid-State Sensor Electrode Based on Titanium Thin Film as an Indicator Electrode in Potentiometric and Conductometric Acid-Base Titration in Aqueous Solution

الملخص EN

A modified Ti/(SnO2 + Sb2O3) electrode was prepared by thermal deposition on titanium substrate and its use as indicator electrode to potentiometric and conductometric acid-base titration in aqueous solution at 298 K was developed.

The E-pH curve is linear with slope of 0.0512 V/dec at 298 K.

The standard potential of this electrode, E0, was determined with respect to the SCE as reference electrode.

The recovery percentages for potentiometric and conductometric acid-base titration for acetic acid against NaOH were calculated.

The cell constant, specific conductance, and the molar conductance with dilution for some common electrolytes were measured.
