CH₃COONa(s) (Sodium acetate or sodium ethanoate)
Sodium acetate is a salt of a weak acid (acetic acid, CH₃COOH) and a strong base (sodium hydroxide, NaOH). When it undergoes hydrolysis, it produces a basic solution due to the hydrolysis of the acetate ion:

CH₃COO⁻ + H₂O → CH₃COOH + OH⁻

The hydroxide ions (OH⁻) produced in this reaction increase the pH of the solution, making it alkaline.

The other options do not produce an alkaline solution upon hydrolysis:
- A. NH₄Cl(s) (Ammonium chloride) produces an acidic solution.
- B. AlCl₃(s) (Aluminum chloride) produces an acidic solution.
- D. NH₄NO₃(s) (Ammonium nitrate) produces an acidic solution.
