Design an experiment to demonstrate how a strong oxidizing agent affects the equilibrium of a redox reaction.

• A. Use permanganate ion to oxidize iron 2 ions and measure the concentration of products over time.
• B. Use dichromate ion to oxidize sodium chloride and measure the temperature change.
• C. Use cerium 4 ion to oxidize carbon dioxide and measure the pressure change.
• D. Use triiodide ion to oxidize water and measure the concentration of reactants over time.

Answer: (A)
