`Zn(s) + Cu^(2+)(aq) rarr Zn^(2+)(aq) + Cu(s)` The cell representation for the above redox reaction is

Options

A. `Zn | Zn^(2+) || Cu^(2+) |Cu`
B. `Cu | Cu^(2+) || Zn^(2+) | Zn`
C. `Cu|Zn^(2+) || Zn | Cu^(2+)`
D. `Cu^(2+) | Zn || Zn^(2+) | Cu`

Answer

A

Explanation

Electrode on which oxidation occurs is written on L.H.S. and the other on the R.H.S. as represented by-
`Zn | Zn^(2+) || Cu^(2+) |Cu`
