Chlorine dioxide is not the same as chlorine. While chlorine dioxide has “chlorine” in its name, its chemistry is
very different from that of chlorine. Although both chlorine dioxide and chlorine are oxidising agents (or electron
receivers), chlorine dioxide is significantly more effective as a biocide and disinfectant than chlorine. This is
because chlorine molecules have the capacity to accept only two electrons, whilst chlorine dioxide has
the capacity to accept five.
