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 Ka = 1.8 × 10-5 for HC2H3O2.

pH________

Please shown your work for these problem.
