Zn + Cu²⁺ → Zn²⁺ + Cu
Explanation:
The overall equation of this redox reaction is combination of the two half equations. The similar species on both sides are cancelled out leaving a net overall reaction:
Zn → Zn²⁺ + 2e⁻ oxidation step
Cu²⁺ + 2e⁻ → Cu reduction step
Combining both equations:
Zn + Cu²⁺ + 2e⁻ → Zn²⁺ + 2e⁻ + Cu
since the common specie on both sides is 2e⁻, they cancel out to give an overall reaction:
Zn + Cu²⁺ → Zn²⁺ + Cu
