The pOH of an aqueous solution of 0.397 M hypochlorous acid is?

The pOH of an aqueous solution of 0.397 M hypochlorous acid is?

Homework Answers

Answer #1

hypochlorous acid = weak acid

pka of hypochlorous acid = 7.53

pH of weak acid = 1/2(pka-logC)

                          = 1/2(7.53-log0.397)

                         = 3.96

pOH = 14-pH

        = 14-3.96

        = 10.04

A student is asked to determine the value of Ka for hypochlorous acid by titration with potassium hydroxide. The student begins titrating a 48.5 mL sample of a 0.384 M aqueous solution of hypochlorous acid with a 0.269 M aqueous potassium hydroxide solution, but runs out of standardized base before reaching the equivalence point. The student's last observation is that when 24.5 milliliters of potassium hydroxide have been added, the pH is 7.235. What is Ka for hypochlorous acid based...
