Answer:
Approximately under standard conditions.
Explanation:
Equation for the overall reaction:
.
Write down the ionic equation for this reaction:
.
The net ionic equation for this reaction would be:
.
In this reaction:
- Zinc loses electrons and was oxidized (at the anode):
.
- Copper gains electrons and was reduced (at the cathode):
.
Look up the standard potentials for each half-reaction on a table of standard reduction potentials.
Notice that is oxidation and is likely not on the table of standard reduction potentials. However, the reverse reaction,
, is reduction and is likely on the table.
for
, and
for
The reduction potential of would be
, the opposite of the reverse reaction
.
The standard potential of the overall reaction would be the sum of the standard potentials of the two half-reactions:
.
