The pKa of hypochlorous acid is 7.530. A 59.0 mL solution of 0.142 M sodium hypochlorite (NaOCI) is titrated with 0.272 M HCI. Calculate the pH of the solution a) after the addition of 11.3 mL of 0.272 M HC Number b) after the addition of 32.8 mL of 0.272 M HC Number pH-II c) at the equivalence point with 0.272 M HCI. Number
