Laundry bleach is a solution of hypochlorus acid (HClO). To determine the HClO content of bleach, an aqueous sulfide salt is added to the bleach solution. The balanced equation for the reaction is: HClO(aq) + S2-(aq) --> Cl-(aq) + OH-(aq) + S(s) The resulting chloride is then precipitated as AgCl. When 25.0 mL of laundry bleach (d = 1.02 g/mL) is treated as described above, 3.49 g of AgCl are obtained. What is the mass % of HClO in the bleach.
