The individual activity of hypochlorite ion in concentrated neutral salt (NaCl-NaClO3) solutions has been estimated kinetically by measurement of the Faradaic efficiency in a chlorate producing system comprised of a cell and external reactor, with provision for brine re-circulation. By use of this activity in the diffusion relationships developed by Ibl and Landolt [1-3], reasonable agreement has been achieved between the experimental chlorate yield and the yield expected based on the combined hydrolytic and diffusional flux of active chlorine. In this way it has been shown as expected from basic theory that the gradient of chemical potential rather than the concentration difference represents the driving force of diffusion. A formal activity coefficient for active chlorine species is suggested as being a useful term when considering the chlorate cell system.
