Gallium is obtained by electrolysis of its chlorides. Write the anode and cathode electrode equations which occur if you were to electrolyse molten gallium chloride and give the overall balanced equation.

1 answer

Anode: 2Cl^- (l) → Cl2 (g) + 2e^-

Cathode: Ga^3+ (l) + 3e^- → Ga (l)

Overall balanced equation: 2GaCl3 (l) → 2Ga (l) + 3Cl2 (g)
