Hypochlorous acid (HOCl) is a weak acid with a pKa = 7.53 that is used as a disinfectant. a. You need to add 200 mg/L of HOCl to water at a pH = 6.5 in order to properly disinfect water. What is the resulting pH of this solution? b. The OCl- form of this acid is less effective as a disinfectant. Calculate the ration of [HOCl]/[OCl-] at pH=4 and pH=11 c.When you are trying to use this acid to disinfect, is it better to use this acid at a low pH or a high pH?
