Abstract

An electrode having an electrocatalytic surface or coating composed of a mixture with iridium oxide is used in a reversible polarity electrolytic cell to selectively produce an alkali metal hypohalite, preferably sodium hypochlorite, from brine made from hard water. The mixture also may have a platinum group metal oxide and a valve metal oxide, preferably, ruthenium oxide and titanium oxide respectively.
