What is the role of Cu(II) ions in the iodometry reaction?

What is the role of Cu(II) ions in the iodometry reaction?

Options

  1. ACu(II) ions reduce iodine to iodide ions.
  2. BCu(II) ions oxidize iodide ions to iodine.
  3. CCu(II) ions complex with iodine to form Cu2I2.
  4. DCu(II) ions precipitate with iodine.

Correct answer

B. Cu(II) ions oxidize iodide ions to iodine.

Step-by-step solution

Cu(II) ions act as an oxidizing agent, converting iodide ions (I⁻) to iodine (I2) in the reaction.
