Which of the following metal does not react with the solution of copper sulphate

Options

A. Mg
B. Fe
C. Zn
D. Ag

Answer

To determine which metal does not react with a solution of copper sulfate (CuSO4), we can follow these steps:

### Step 1: Understand the Reactivity Series
The reactivity series is a list of metals arranged in order of decreasing reactivity. Metals higher in the series can displace metals lower in the series from their compounds. For example, if a metal is more reactive than copper, it can displace copper from copper sulfate.

### Step 2: Identify the Metals in the Question
Let's consider the metals typically mentioned in such questions. Common metals include:
- Potassium (K)
- Sodium (Na)
- Calcium (Ca)
- Magnesium (Mg)
- Aluminum (Al)
- Zinc (Zn)
- Iron (Fe)
- Copper (Cu)
- Silver (Ag)
- Gold (Au)

### Step 3: Analyze the Reactivity of Each Metal
- **Potassium, Sodium, Calcium, Magnesium**: These metals are highly reactive and will react with copper sulfate.
- **Aluminum**: This metal is also reactive and can react with copper sulfate.
- **Zinc**: Zinc is more reactive than copper and will react with copper sulfate.
- **Iron**: Iron is more reactive than copper and will also react with copper sulfate.
- **Copper**: Copper cannot displace itself from copper sulfate; hence it will not react.
- **Silver**: Silver is less reactive than copper and will not displace copper from copper sulfate.
- **Gold**: Gold is also less reactive than copper and will not react.

### Step 4: Conclusion
From the analysis, the metals that do not react with copper sulfate are Silver (Ag) and Gold (Au). However, if we are asked to choose one option, Silver (Ag) is the most commonly referenced metal that does not react with copper sulfate.

### Final Answer
The metal that does not react with the solution of copper sulfate is **Silver (Ag)**.
