Question

Consider the hall reactions below for a chemical reaction

Answer 1

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
