摘要

PURPOSE: A hypochlorous acid solution and a production method thereof are provided to raise pH of a solution while a concentration of an active chlorine in solution is not reduced. CONSTITUTION: A pH of a hypochlorous acid solution is raised through a reaction formula of HCl + H2O2 HOCl + H2O by containing a step in which oxygenated water is added to the hypochlorous acid solution with a hydrochloric acid.
