The aqueous solution of which of the following salt is basic?
Correct answer: C. CH₃COONa
- A. NH₄Cl
- B. NaCl
- C. CH₃COONa
- D. NaNO₃
Explanation
The correct answer is CH₃COONa. When CH₃COONa is dissolved in water, it dissociates into CH₃COO⁻ and Na⁺ ions. The CH₃COO⁻ ion can react with water to form CH₃COOH and OH⁻, leading to a basic solution. In contrast, NH₄Cl forms an acidic solution, while NaCl and NaNO₃ form neutral solutions because they are salts derived from strong acids and strong bases, which do not affect the pH of the solution significantly.
