Analysis of bleach involves two sequential redox reactions: First, bleach is reacted in acid solution with excess iodide anion to produce yellow-colored Review I Constants I Periodic Table lodine: A sample of a new cleaning product, "Joe's Famous Bleach Cleaner," with a mass of 49.0 g, was diluted with an acetic acid solution containing excess I.A small amount of starch indicator CIO+ 2H+2112+ CI+ H20 solution was then added, turning the solution a deep bluish-purple. The solution was then titrated with 0.260 M sodium thiosulfate, Na25203, containing the lon S203. A volume of 40.0 mL of sodium thiosulfate, the titrant, was needed to turn the solution colorless. Then, to determine how much of the lodine was formed, the solution is titrated with sodium thiosulfate solution: I2 + 282032I+ S40 Percent composition A bit of starch is added to the titration reaction. Starch is intensely blue in the presence of I2. The solution thus turns from deep blue to colorless at the reaction equivalence point. To obtain percent composition by mass, use the equation given here: mass due to specific compone percent composition-total mass of the mixture 100% • Part A What is the percentage composition by mass of NACIO in the bleach product?
