Hypochlorous acid is a weak acid and will disassociate according to: HOCl → H+ + OCl— In waters with pH between 6.5 and 8.5,the reaction is incomplete and both species (HOCl and OCl—) will be present.Hypochlorous acid is the more germicidal of the two. A relatively strong oxidizing agent,chlorine can react with a wide variety of compounds.
