The correct Answer is:
To solve the question, we will evaluate each statement one by one to determine their correctness. ### Step-by-Step Solution: **Statement 1:** Ferric bromide is obtained when chlorine gas is bubbled through a solution of ferrous bromide. 1. **Identify the reactants:** We have ferrous bromide (FeBr₂) and chlorine gas (Cl₂). 2. **Write the reaction:** When chlorine gas is bubbled through ferrous bromide, the reaction can be written as: \[ 2 \text{FeBr}_2 + 3 \text{Cl}_2 \rightarrow 2 \text{FeCl}_3 + 4 \text{Br}_2 \] 3. **Analyze the products:** The products of this reaction are ferric chloride (FeCl₃) and bromine (Br₂), not ferric bromide (FeBr₃). 4. **Conclusion:** The first statement is **false**. **Statement 2:** Sodium sulphate is obtained when SO₂, H₂O, and air are passed over heated sodium chloride. 1. **Identify the reactants:** We have sodium chloride (NaCl), sulfur dioxide (SO₂), water (H₂O), and oxygen (from air). 2. **Write the reaction:** The reaction can be represented as: \[ 2 \text{NaCl} + \text{SO}_2 + 2 \text{H}_2\text{O} + \text{O}_2 \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{HCl} \] 3. **Analyze the products:** The products of this reaction include sodium sulfate (Na₂SO₄) and hydrochloric acid (HCl). 4. **Conclusion:** The second statement is **true**. **Statement 3:** H₂S gas is liberated when aluminium sulfide becomes damp. 1. **Identify the reactants:** We have aluminium sulfide (Al₂S₃) and water (H₂O). 2. **Write the reaction:** The reaction can be represented as: \[ \text{Al}_2\text{S}_3 + 6 \text{H}_2\text{O} \rightarrow 2 \text{Al(OH)}_3 + 3 \text{H}_2\text{S} \] 3. **Analyze the products:** The products include aluminium hydroxide (Al(OH)₃) and hydrogen sulfide (H₂S). 4. **Conclusion:** The third statement is **true**. ### Final Conclusion: - **Statement 1:** False - **Statement 2:** True - **Statement 3:** True Thus, the correct option is that **Statements 2 and 3 are correct**.
