Redox Reactions

Question 1

Write the balanced ionic half equations from this ionic equation, Mg (s) + Cu²⁺ (aq) —> Mg2+ (aq) + Cu (s)

Answer 1

Oxidation: Mg (s) —> Mg2+ (aq)
Reduction: Cu²⁺ (aq) —> Cu (s)

After balancing:
Oxidation: Mg (s) —> Mg2+ (aq) + 2e-
Reduction: Cu²⁺ (aq) + 2e- —> Cu (s)
