The dissociation of HOCI to your much less microbicidal sort (hypochlorite ion OCl‑) relies on pH. The disinfecting efficacy of chlorine decreases with a rise in pH that parallels the conversion of undissociated HOCI to OCl‑ 329, 526. A possible hazard is production of the carcinogen bis(chloromethyl) ether when hypochlorite solutions contact formaldehyde 527 as well as the manufacture of the animal carcinogen trihalomethane when very hot h2o is hyperchlorinated 528.
