Answer:
Cd²⁺(aq) + 2 e⁻ → Cd(s)
Mg(s) → Mg²⁺(aq) + 2 e⁻
Cd²⁺(aq) + Mg(s) → Cd(s) + Mg²⁺(aq)
Explanation:
A voltaic cell is composed of two half-reactions:
Reduction (cathode): Cd²⁺(aq) + 2 e⁻ → Cd(s)
Oxidation (anode): Mg(s) → Mg²⁺(aq) + 2 e⁻
Cd²⁺ reduces to Cd (the oxidation number decreases from 2 to 0), whereas Mg oxidizes to Mg²⁺ (the oxidation number increases from 0 to 2). We can get the overall cell reaction by adding both half-reactions:
Cd²⁺(aq) + 2 e⁻ + Mg(s) → Cd(s) + Mg²⁺(aq) + 2 e⁻
Cd²⁺(aq) + Mg(s) → Cd(s) + Mg²⁺(aq)
