Question

An aqueous ScCl₃ solution is electrolyzed under 1 bar pressure using platinum electrodes.

(a) Write the half-reactions predicted to occur at the anode and cathode, based on the standard cell potentials given below.

Standard Reduction Potentials (Volts) at 25 °C
Cl₂(g) + 2 e^- 2 Cl^-(aq)	1.360
O₂(g) + 4 H₃O⁺(aq) + 4 e^- 6 H₂O(l)	1.229
2 H₂O(l) + 2 e^- H₂(g) + 2 OH^-(aq)	-0.828
Sc³⁺(aq) + 3 e^- Sc(s)	-2.080

Half-reaction at anode:
