In the titration of potassium permanganate $\left(\mathrm{KMnO}_4\right)$ against Ferrous ammonium sulphate (FAS) solution, dilute sulphuric acid but not nitric acid is used to maintain acidic medium, because

  • A
    It is difficult to identify the end point
  • B
    Nitric acid doesn't act as an indicator
  • Correct answer
    C
    Nitric acid itself is an oxidizing agent
  • D
    Nitric acid is a weak acid than sulphuric acid

Solution

Nitric acid is not used in the redox titration because it is a strong OA itself.

Hence, the correct answer is option: 'C'.
