What happens when a nickel rod is dipped into a copper sulphate solution ? Justify your answer.
`[E_(Ni^(+2)//Ni)^@=0*25V and E_(Cu^(+2)//Cu)^@=+0*34V]`

Explanation

To solve the question of what happens when a nickel rod is dipped into a copper sulfate solution, we can follow these steps:

### Step 1: Understand the Electrochemical Series
The electrochemical series ranks metals based on their standard electrode potentials (E°). A higher E° value indicates a greater tendency to be reduced (gain electrons), while a lower E° value indicates a greater tendency to be oxidized (lose electrons).

### Step 2: Identify the Standard Electrode Potentials
From the question, we have:
- E° for nickel (Ni²⁺/Ni) = -0.25 V
