Write a procedure that a laboratory technician could use to prepare 2.0 L of 0.25 mol/L sulfuric acid, H2S04(aq), using 12.0 mol/L stock solution. Include appropriate safety precautions. Hypochlorous acid, HOCl(aq), is a weak acid that is used as a bleach and a disinfectant. When 25.00 mL samples of hypochlorous acid were titrated with 1.00 mol/L sodium hydroxide, NaOH(aq), an average of 19.15 mL of sodium hydroxide was needed to neutralize the acid. Calculate the molar concentration of the hypochlorous acid.
