The titration gives unsatisfactory result when carried out in the presence of HCl,HCl,HCl, because HClHClHCl :Agets oxidised by oxalic acid to chlorineBfurnishes H+{H^ + }H+ ions in addition to those from oxalic acidCreduces permanganate to Mn2+M{n^{2 + }}Mn2+Doxaidises oxalic acid to carbon doxide and waterCheck answerSkip
