WebWhat happens when potassium iodide reacts with water? This reaction happens in preference to the reduction of potassium partially because reduction of potassium ions would produce potassium metal, which would immediately react with the water, oxidising again to potassium hydroxide and hydrogen gas. The net reaction is the same.
