odium hydroxide, NaOH, is also known as lye or caustic soda. Electrolysis of concentrated sodium chloride solutions (brine) produces chlorine gas, hydrogen gas and aqueous sodium hydroxide. Cl2(g) is produced at the anode (positive electrode). H2(g) and NaOH(aq) are produced at the cathode (negative electrode).
