The hypochlorous acid in the presence of oxidisable matter gives off its oxygen; hydrochloric acid being left.
It is decomposed by acids with the evolution of chlorine and oxygen (hypochlorous acid).
hypochlorous acid first reddens, and then bleaches, litmus-paper.
The loss can be explained by the decomposition of hypochlorous acid, in the presence of light, into hydrochloric acid and oxygen.
The chlorine present as hypochlorous acid increased slightly but the quantity never exceeded very small proportions.
One of the most important derivatives of hypochlorous acid is bleaching powder.
hypochlorous acid hy·po·chlo·rous acid (hī'pə-klôr'əs)
A weak but strongly oxidizing acid produced by the reaction of chlorine and water and used as a bleaching agent, disinfectant, and chlorinating agent.
