Which of the following forms a basic salt solution?A. SnCl2B. NaClC. NH4ClD. CH3COONaE. FeCl3

To determine which of the options forms a basic salt solution, we need to consider the nature of the cation and anion in each compound.

A. SnCl2: This compound contains the cation Sn2+ and the anion Cl-. Since neither the cation nor the anion is derived from a strong base or acid, SnCl2 does not form a basic salt solution.

B. NaCl: This compound contains the cation Na+ and the anion Cl-. NaCl is a neutral salt and does not form a basic solution.

C. NH4Cl: This compound contains the cation NH4+ and the anion Cl-. NH4Cl is derived from the weak base NH3 (ammonia) and the strong acid HCl. Therefore, NH4Cl does not form a basic salt solution.

D. CH3COONa: This compound contains the cation Na+ and the anion CH3COO-. CH3COONa is derived from the weak acid CH3COOH (acetic acid) and the strong base NaOH. Therefore, CH3COONa can form a basic salt solution.

E. FeCl3: This compound contains the cation Fe3+ and the anion Cl-. FeCl3 is derived from the strong acid HCl and does not form a basic salt solution.

Based on the analysis above, the compound that forms a basic salt solution is D. CH3COONa.
