Transition metals can act as catalysts because these can change their oxidation state. How does Fe(III) catalyze the reaction between iodide and persulfate ions?

Options

  1. AFe(III) acts as a reducing agent.
  2. BFe(III) acts as an oxidizing agent.
  3. CFe(III) provides a surface for the reaction to occur.
  4. DFe(III) changes its oxidation state during the reaction.

Correct answer

D. Fe(III) changes its oxidation state during the reaction.

Step-by-step solution

Correct Option is : (D) Fe(III) changes its oxidation state during the reaction.
