In the permanganate titration, the solution of reductant is always made acidic by adding `H_(2)So_(4)` rather than HCl or `HNO_(3)` because :

Options

A. HCl is a reducing agent and it may get oxidized itself resulting into decrease in the volume of`KMnO_(4)` equivalent to the reducing agent under estimation.
B. `HNO_(3)` is an oxidizing agent and it may get reduced into consumption of more volume of`KMnO_(4)` for the end point.
C. `H_(2)SO_(4)` (dil.) is neither oxidizing nor reducing agent.
D. HCl and`HNO_(3)` are more costlier than`H_(2)SO_(4)` .

Answer

C

Explanation

HCI can act as a reducing agent& therby interering with the titattion Similar,y,HNO_(2)mis good oxidising agent
