Question 1

Sodium hypochlorite, NaOCl, is the active ingredient in household bleach. What is the concentration of hypochlorite ion if 20.00 mL of bleach requires 31.00 mL of 0.500 M HCl to reach the equivalence point?
◦ 0.333 M
◦ 0.775 M
◦ 1.28 M
◦ 0.275 M

Question 2

What is the pH at the equivalence point of a weak base-strong acid titration if 20.00 mL of NaOCl requires 28.30 mL of 0.20 M HCl? Ka = 3.0 × 10-8 for HOCl.
◦ 4.23
◦ 3.76
