Answer:
Explanation: Zn (s) + 2 AgCl (s) ⇒ ZnCl2 (s) + 2 Ag(s)
Less noble Zinc reduces more noble Silver
Two Half Cell reactions are as follow,
3e⁻ + Al⁺³ → Al (Reduction Reaction)
Mg → Mg⁺² + 2e⁻ (Oxidation Reaction)
In order to balance the number of electrons, multiply reduction reaction by 2 and oxidation reaction by 3.
So,
6e⁻ + 2 Al⁺³ → 2 Al
3 Mg → 3 Mg⁺² + 6e⁻ (e⁻ cancelled)
_______________________
2 Al⁺³ + 3 Mg → 2 Al + 3 Mg⁺²
Result:
At Anode Magnesium metal is Oxidized and At Cathode Aluminium Ions are reduced.
