Potassium hypochlorite, KOCl

An aqueous solution of the Potassium hypochlorite, KOCl, is formed analogously to that of sodium hypochlorite by the action of chlorine on a dilute aqueous solution of the hydroxide at low temperatures; by the interaction of potassium salts and bleaching- powder solution; and by the electrolysis of potassium-chloride solution without a diaphragm.. It is also formed to some extent by passing an alternating current through a solution of potassium chloride. The heat of formation of the substance in aqueous solution is given as 84.35 Cal. And 88.0 Cal. This solution was formerly employed as a bleaching agent, under the name "Eau de Javelle."
