We’re being asked to determine which metal is being oxidized given the following reaction.
Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)
Recall the mnemonics LEO GER.
We’ll identify the anode and cathode half-reactions using the following steps.
Step 1. Separate the overall reaction into two half-reactions
Step 2. Balance the elements in each half-reaction.
A Cu-Zn voltaic cell based on the reaction in the equation given below.
Zn( s ) + Cu2 + ( aq ) → Zn2 + ( aq ) + Cu( s )
Which metal is oxidized in this voltaic cell?
