23.9: Electrolysis of Water - Chemistry LibreTexts

Electrolysis of Water. The electrolysis of water produces hydrogen and oxygen gases. The electrolytic cell consists of a pair of platinum electrodes immersed in water to which a small amount of an electrolyte such as H 2 SO 4 has been added. The electrolyte is necessary because pure water will not carry enough charge due to the lack of ions.

Therefore, reduction of water is the hode reaction when the aqueous NaCl is electrolysed. Oxidation half-reaction at anode: At anode, there will be competition between oxidation of Cl – ion to Cl 2 gas as in the case of molten NaCl and the oxidation of water to O 2 gas. i. Oxidation of Cl - ions to chlorine gas.
