Constants Periodic Table Analysis of bleach involves two sequential redox reactions: First, bleach is reacted in acid solution with excess iodide anion to produce yellow-colored iodine: Clo- + 2H+ + 21-→I2 + Cl + H2O A sample of a new cleaning product. "Joe's Famous Bleach Cleaner," with a mass of 68.0 g, was diluted with an acetic acid solution containing excess I". A small amount of starch indicator solution was then aded, turning the solution a deep bluish-purple.
