A cell is prepared by dipping a copper rod in `1 MCuSO_(4)` solution and a nickel rod in `1M NiSO_(4)`. The standard reduction potentials of copper and nickel electrodes are `+0.34 V` and `-0.25 V` respectively.
(i) Which electrode will work as anode and which as cathode?
(ii) What will be the cell reaction?
(iii) How is the cell represented ?
(iv) Calculate the `EMF` of the cell.

Explanation

To solve the problem step by step, we will address each part of the question sequentially.

### (i) Which electrode will work as anode and which as cathode?

1. **Identify the standard reduction potentials**:
- Copper (Cu) has a standard reduction potential of \( +0.34 \, \text{V} \).
- Nickel (Ni) has a standard reduction potential of \( -0.25 \, \text{V} \).
