Explain why the color of KMnO 4 disappears when oxalic acid is added to its solution in acidic medium.

Options

  1. AOxalic acid reduces Mn(VII) to Mn(II), resulting in a colorless solution.
  2. BOxalic acid oxidizes Mn(VII) to Mn(IV), resulting in a colorless solution.
  3. COxalic acid reacts with KMnO 4 to form a colorless compound.
  4. DOxalic acid forms a complex with KMnO 4 , masking its color.

Correct answer

B. Oxalic acid oxidizes Mn(VII) to Mn(IV), resulting in a colorless solution.

Step-by-step solution

Correct Option is : (B) Oxalic acid oxidizes Mn(VII) to Mn(IV), resulting in a colorless solution.
