How to find | Electrolysis of Sodium Chloride Half Reaction
How to find the oxidation half-reaction and the reduction half-reaction in the Electrolysis of Sodium Chloride in an Electrolytic cell.
Electrolysis of NaCl (molten) Half Reactions are as follows:
Cl- ions that collide with the positive electrode are oxidized to Cl2 gas, which bubbles off at the anode. At Anode(+ve electrode) Oxidation half-reaction occurs. When Na+ ions collide with the negative electrode, the battery carries a large enough potential to force these ions to pick up electrons to form sodium metal. At Cathode( -ve electrode) Reduction half-reaction occurs. The net effect of passing an electric current through the molten NaCl in the cell decomposes it into its elements, Sodium metal & chlorine gas.
