A salt of chloric acid (HClO3), i.e., containing the chlorate ion; the term chlorates may include other ions: hypochlorite (ClO-), chlorite (ClO-), and perchlorate (ClO-), all strong oxidizing, disinfecting, and bleaching agents. They also can form explosive mixtures with other chemicals. Chlorate is a potential contaminant of drinking water when chlorine dioxide (ClO2) is used for disinfection; it is formed from the hypochlorite ion or hypochlorous acid (HClO):
Chlorate ions are also formed during the decomposition of bleach or sodium hypochlorite (NaOCl) or in ozonated water that contains a chlorine residual. Chlorates may cause hemolysis, methemoglobinemia, renal failure, or even death at high concentrations, e.g., 71 mg/kg of body weight. See also perchlorate.
