Potentometry Method is highly accurate method due to its result obtain up to 4 decimal which is impossible in case of manual titration also in some cases we needs to add mercuric acetate which combine with free chloride which may obtained from Hcl present in sample and form mercuric chloride etherwise it interfare in titramatric reaction
