Chemistry of Chlorites

“…The formation of chlorites is a slow reaction which limits the rate of chlorate formation. Since for rapid formation of chlorate it is necessary to overchlorinate the alkali, the equation is frequently written to indicate that hypochlorous acid and hypochlorite ion participate in the reaction: (12) The intermediate formation of chlorites may be represented by such equations as:…”

“…The formation of chlorites is a slow reaction which limits the rate of chlorate formation. Since for rapid formation of chlorate it is necessary to overchlorinate the alkali, the equation is frequently written to indicate that hypochlorous acid and hypochlorite ion participate in the reaction: HCIO + 2C10-= H+ + CIOs" + 2C1" (12) The intermediate formation of chlorites may be represented by such equations as: 2NaC10 = NaClOa + NaCI (13) NaClOa + NaCIO = NaCIO, + NaCI (14) Chlorine dioxide has also been observed as a product of the reaction of hypochlorites upon chlorites. Foerster and Doleh (14) believed that chlorate was the primary product and that chlorine dioxide was formed by the reaction of chlorous and chloric acids.…”

“…Figure 2 also includes a curve showing the per cent hydrolysis of sodium hypochlorite at different pH values. These data are taken from the tabulations of Elod and Vogel (12) and Opfermann and Hochberger (86). At low values of pH where chlorine dioxide is stable, free chlorine and hypochlorous acid are both present.…”
