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

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,e 0,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. © 2012 nasser abu ghalwa.
