Question:

A 0.150 M solution of NaClO is prepared by dissolving NaClO in water. A 50.0-mL sample of this solution is titrated with 0.100 M HCl. Calculate the pH of the solution at each of the following points of the titration:
(a) Prior to the addition of any HCl;
(b) Halfway to the equivalence point;
(c) At the equivalence point;
(d) After 5.00 mL of HCl has been added beyond the equivalence point. Ka for HClO is 3.5 × 10-8.
