Two beakers A and B contain iron(II) sulphate solution in the beaker A a small piece of copper is added and in the beaker B a small piece of zinc is added it is found that a grey deposit forms on the zinc but nothing is deposited on the copper from these observations it can be concluded that

Options

A. Zinc is most active metal followed by iron and copper respectively
B. Zinc is most active metal followed by copper and iron respectively
C. iron is most active metal followed by zinc and copper respectively
D. iron is most active metal followed by copper and zinc respectively

Answer

To solve the problem, we need to analyze the reactions taking place in both beakers A and B and draw conclusions based on the observations.

### Step-by-Step Solution:

1. **Identify the Solutions in Beakers**:
- Beaker A contains iron(II) sulfate (FeSO₄) solution.
- Beaker B also contains iron(II) sulfate (FeSO₄) solution.

**Hint**: Always start by identifying the reactants involved in the chemical reactions.

2. **Add Copper to Beaker A**:
- A small piece of copper is added to the iron(II) sulfate solution in Beaker A.
- No reaction occurs, and no grey deposit is formed on the copper.

**Hint**: Consider the reactivity of copper compared to iron. What does this imply about the ability of copper to displace iron?

3. **Add Zinc to Beaker B**:
- A small piece of zinc is added to the iron(II) sulfate solution in Beaker B.
- A grey deposit is formed on the zinc, indicating a reaction has taken place.

**Hint**: Think about the reactivity series of metals. Which metal is more reactive, zinc or iron?

4. **Analyze the Observations**:
- Since no reaction occurred in Beaker A with copper, it indicates that copper cannot displace iron from iron(II) sulfate because copper is less reactive than iron.
- In Beaker B, zinc displaces iron from iron(II) sulfate, forming zinc sulfate (ZnSO₄) and depositing iron, which is observed as a grey deposit.

**Hint**: Reflect on the reactivity series: which metals can displace others from their compounds?

5. **Conclude Based on Reactivity**:
- From the observations, we conclude that zinc is more reactive than iron, and copper is less reactive than iron.
- Therefore, the order of reactivity is: Zinc > Iron > Copper.

**Hint**: Summarize your findings based on the reactions and the reactivity series.

### Final Conclusion:
From the observations made in the experiment, it can be concluded that zinc is more reactive than iron, and copper is less reactive than iron. This is consistent with the reactivity series of metals.
