Assertion : Silver can displace copper from `CuSO_4` solution.
Reason : Silver is placed below copper in the electrochemical series.

Options

A. If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.
B. If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.
C. If Assertion is CORRECT but Reason is INCORRECT.
D. If Assertion is INCORRECT but Reason is CORRECT.

Answer

To solve the question regarding the assertion and reason about silver and copper, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Silver can displace copper from CuSO4 solution." To evaluate this, we need to consider the principles of displacement reactions in terms of the electrochemical series.

2. **Understanding the Reason**: The reason states that "Silver is placed below copper in the electrochemical series." This is a crucial point because the position of metals in the electrochemical series determines their ability to displace one another in reactions.

3. **Electrochemical Series**: In the electrochemical series, metals are arranged based on their standard reduction potentials. The higher the reduction potential, the more likely a metal ion will be reduced (gain electrons).

4. **Reduction Potentials**:
- For copper (Cu²⁺ + 2e⁻ → Cu), the standard reduction potential (E°) is +0.34 V.
- For silver (Ag⁺ + e⁻ → Ag), the standard reduction potential (E°) is +0.80 V.
- Since silver has a higher reduction potential than copper, it means that silver ions (Ag⁺) are more likely to gain electrons and be reduced compared to copper ions (Cu²⁺).

5. **Displacement Reaction**: In a displacement reaction, a more reactive metal displaces a less reactive metal from its compound. Since silver has a higher reduction potential than copper, silver cannot displace copper from its compound (CuSO4). Instead, copper will remain in the solution, and silver ions will be reduced to solid silver.

6. **Conclusion**:
- The assertion is **false** because silver cannot displace copper from CuSO4 solution.
- The reason is **true** because silver is indeed placed below copper in the electrochemical series.

7. **Final Answer**: Therefore, the correct option is that the assertion is false, but the reason is true.
