Question

Answer the following questions for titration of 10.00 mL of a hypochlorous acid solution with a 0.09975 M sodium hydroxide.

1. If 20.05 mL of the sodium hydroxide solution were required to reach the endpoint in the titration, what was the original concentration of the hypochlorous acid solution?

2. What was the initial pH of the hypochlorous acid solution (before any sodium hydroxide was added)?

3. What was the pH in the titration after addition of 4.01 mL of NaOH?

4. What was the pH in the titration at the equivalence point?
