A student is asked to determine the value of Ka for hypochlorous acid by titration with barium hydroxide. The student begins titrating a 48.4 mL sample of a 0.451 M aqueous solution of hypochlorous acid with a 0.306 M aqueous barium hydroxide solution, but runs out of standardized base before reaching the equivalence point. The student's last observation is that when 22.6 milliliters of barium hydroxide have been added, the pH is 7.675. What is Ka for hypochlorous acid based...
