Question

Consider the line notation of a galvanic cell described below.
Mg|Mg^2+||Al^3+|Al

1. Sketch the galvanic cell based on the above half-reactions and shows the direction of the electrons flow, and identify the cathode and the anode.

Answer 1

In the given cell notation "Mg|Mg^2+||Al^3+|Al", the left side represents the anode and the right side represents the cathode.

Sketch of the galvanic cell:

Anode (left side): Mg(s) | Mg^2+ (aq) || Cathode (right side): Al^3+ (aq) | Al (s)

Direction of electron flow: From the Mg anode to the Al cathode.

Cathode: Al (s) - Reduction occurs at the Al cathode.

Anode: Mg (s) - Oxidation occurs at the Mg anode.
