nature : often called electrolysis. Chlorine and caustic soda manufacturers of the important ways. Net system saturated salt solution into electrolyzer, when DC passed, which happened electrolysis reaction produced ion migration and discharge. Solution of anionic (Cl - / sup> - ) towards the anode and discharge, ion (Na + / sup > or H + / sup>) towards the cathode and discharge. Ordinary solid cathode electrode reaction is the result : Health chlorine at the anode, cathode production of caustic soda solution and hydrogen. Caustic soda solution by evaporation can be obtained after the liquid or solid caustic soda. Chlorine and hydrogen can be used. This method used by the electrolyzer a mercury cell, the diaphragm cell membrane and other electrolyzer. When the salt solution at hydroelectric not divide, chlorine and sodium hydroxide mixed, with temperatures available sodium chlorate, low sodium hypochlorite when available, it is these two salts series of major production methods.
