The correct Answer is:
To solve the problem, we need to analyze the salts given in Column I and determine their pH characteristics based on the nature of the acids and bases they are derived from. ### Step-by-Step Solution: 1. **Identify the Nature of Each Salt:** - **(A) CH₃COONa (Sodium Acetate):** - This salt is derived from acetic acid (a weak acid) and sodium hydroxide (a strong base). - Since it is formed from a weak acid and a strong base, it will have a basic nature. - **Conclusion:** pH > 7 (Alkaline) 2. **(B) NH₄Cl (Ammonium Chloride):** - This salt is derived from ammonia (a weak base) and hydrochloric acid (a strong acid). - Since it is formed from a strong acid and a weak base, it will have an acidic nature. - **Conclusion:** pH < 7 (Acidic) 3. **(C) NaNO₃ (Sodium Nitrate):** - This salt is derived from nitric acid (a strong acid) and sodium hydroxide (a strong base). - Since both the acid and base are strong, the resulting salt will be neutral. - **Conclusion:** pH = 7 (Neutral) 4. **(D) CH₃COONH₄ (Ammonium Acetate):** - This salt is derived from acetic acid (a weak acid) and ammonia (a weak base). - The pH of this salt can vary but is generally considered to be neutral, as the weak acid and weak base can partially neutralize each other. - **Conclusion:** pH ≈ 7 (Neutral) ### Matching the Salts with Their pH Characteristics: - (A) CH₃COONa → (iii) Alkaline (pH > 7) - (B) NH₄Cl → (ii) Acidic (pH < 7) - (C) NaNO₃ → (iv) Neutral (pH = 7) - (D) CH₃COONH₄ → (i) Almost neutral (pH ≈ 7) ### Final Matching: - A → iii - B → ii - C → iv - D → i ### Summary of the Answer: - A (CH₃COONa) matches with (iii) Alkaline - B (NH₄Cl) matches with (ii) Acidic - C (NaNO₃) matches with (iv) Neutral - D (CH₃COONH₄) matches with (i) Almost neutral
