Liquid chlorine bleach is really nothing more than a

Question

1) Liquid chlorine bleach is really nothing more than a solution of sodium hypochlorite, NaOCl, in water. Usually, the concentration is approximately 5.1% NaOCl by weight. Use this information to calculate the approximate pH of a bleach solution, assuming no other solutes are in the solution except NaOCl. (Assume the bleach has a density of 1.0 g/mL.)

pH_______

2) What is the pH of a solution that contains 0.40 M HC₂H₃O₂ and 0.10 M C₂H₃O₂^-? Use K_a = 1.8 × 10^-5 for HC₂H₃O₂.
