हिन्दीConsider the following statements regarding buffer solutions and salt solubility: (A) The pH of a buffer solution does not change upon dilution. (B) A mixture of ammonium hydroxide and ammonium chloride acts as a basic buffer. (C) A salt with molar solubility \( > 0.1\text{ M} \) is categorized as sparingly soluble. (D) For an acidic buffer, maximum buffer capacity is achieved when \( [\text{Salt}] = [\text{Acid}] \). How many of the above statements are correct?
Correct answer · Option 3
Only three
Explanation
Statements (A), (B), and (D) are correct. (C) is incorrect because salts with solubility \( > 0.1\text{ M} \) are categorized as 'Soluble' (Category I), not sparingly soluble. Thus, exactly three statements are correct.
