Amount of oxalic acid present in a solution can be determined by its titration with KMnO_(4) solution in presence of H_(2)SO_(4) but not in presence of HCI ? Explain why ?

1.	Amount of oxalic acid present in a solution can be determined by its titration with KMnO_(4) solution in presence of H_(2)SO_(4) but not in presence of HCI ? Explain why ?
Answer» SOLUTION :Both oxalic acid and HCI reduce `MbnO_(4)^(-) to Mn^(2+)` `2MnO_(4)^(-)+5C_(2)O_(4)^(2-)+16H^(+)rarr2Mn^(2+)+10CO_(2)+8H_(2)O` `2MnO_(4)^(-)+16 H^(+)+10CI^(-)rarr2Mn^(2+)+8H_(2)O+8H_(2)O+_5CI_(2)`ltbRgt As a result TITRATION does not give us the exact amount of oxalic acid present in the solution
