A 56.0 mL solution of 0.106 M sodium hypochlorite (NaOCl) is titrated with a standardized solution of 0.345 M HCl. The pKa of sodium hypochlorite is 7.53.

A) Draw and label a titration curve showing the reaction above. Include axis labels, pK, and Ve.

B) Neglecting activity, calculate the pH of the solution after the addition of HCl at the equivalence point (Ve), 7.2 mL, 8.6 mL, and 18.2 mL.
