In the titration of potassium permanganate ( KMnO ₄ ) against Ferrous ammonium sulphate (FAS) solution, dilute sulphuric acid but not nitric acid is used to maintain acidic medium, because

Options

  1. AIt is difficult to identify the end point
  2. BNitric acid doesn't act as an indicator
  3. CNitric acid itself is an oxidizing agent
  4. DNitric acid is a weak acid than sulphuric acid

Correct answer

C. Nitric acid itself is an oxidizing agent

Step-by-step solution

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