Full Description

The treatment of drinking water with either NaOCl or Ca(OCl)2 is a source of chlorate ion (ClO3-) in finished water. In basic solution, liquid bleach (NaOCl) decomposition is a second-order process. The decomposition of OCl- involves chlorite ion (ClO2-) as a low concentration intermediate. The reaction of ClO2- to form ClO3- is a fast process, and the ClO2- in liquid bleach is at a concentration of a least 200 times less than the OCl- concentration. The formation of oxygen from decomposing OCl- is a slower side reaction (
