The correct Answer is:
To solve the problem of matching the items in Column-I with those in Column-II, we will analyze each item in Column-I and determine the corresponding statements in Column-II based on the electrolysis reactions. ### Step-by-Step Solution: 1. **Analyzing Column-I:** - **(A) Molten PbCl₂ using inert electrode** - At the cathode: \( \text{Pb}^{2+} + 2e^- \rightarrow \text{Pb (s)} \) (Lead is reduced) - At the anode: \( 2\text{Cl}^- \rightarrow \text{Cl}_2(g) + 2e^- \) (Chloride ions are oxidized) - The solution remains neutral after electrolysis as Pb is deposited and Cl₂ is released. - **Matches with:** (p) "Metal of salt will reduce" and (s) "Solution becomes neutral after electrolysis." 2. **(B) Sodium chloride solution using inert electrode** - At the cathode: \( \text{H}_2\text{O} + 2e^- \rightarrow \text{H}_2(g) + 2\text{OH}^- \) (Water is reduced) - At the anode: \( 2\text{Cl}^- \rightarrow \text{Cl}_2(g) + 2e^- \) (Chloride ions are oxidized) - The solution becomes basic due to the formation of hydroxide ions. - **Matches with:** (q) \( \text{H}_2\text{O} + 2e^- \rightarrow \text{H}_2(g) + 2\text{OH}^- \) and (r) "Solution becomes basic after electrolysis." 3. **(C) Silver nitrate solution with silver electrode** - At the cathode: \( \text{Ag}^+ + e^- \rightarrow \text{Ag (s)} \) (Silver ions are reduced) - At the anode: \( \text{Ag (s)} \rightarrow \text{Ag}^+ + e^- \) (Silver is oxidized) - The solution remains neutral as there are no additional ions produced. - **Matches with:** (p) "Metal of salt will reduce" and (s) "Solution becomes neutral after electrolysis." 4. **(D) Sodium nitrate solution using inert electrode** - At the cathode: \( \text{H}_2\text{O} + 2e^- \rightarrow \text{H}_2(g) + 2\text{OH}^- \) (Water is reduced) - At the anode: \( 2\text{H}_2\text{O} \rightarrow \text{O}_2(g) + 4\text{H}^+ + 4e^- \) (Water is oxidized) - The solution becomes neutral as the number of hydroxide ions produced equals the number of hydrogen ions produced. - **Matches with:** (q) \( \text{H}_2\text{O} + 2e^- \rightarrow \text{H}_2(g) + 2\text{OH}^- \) and (s) "Solution becomes neutral after electrolysis." ### Final Matches: - (A) → (p), (s) - (B) → (q), (r) - (C) → (p), (s) - (D) → (q), (s) ### Summary of Matches: - A → p, s - B → q, r - C → p, s - D → q, s
