Question

Its solution in water will be basic.

पर्याय

• NH₄Cl

• FeCl₃

• CuSO₄

• CH₃COONa

Answer 1

CH₃COONa

Explanation:

Strong acids and weak bases, NH₄Cl and FeCl₃, respectively, form salts. Their salt solutions are hence acidic (pH < 7). Being a salt of a strong acid and a weak base, CuSO₄ has an acidic salt solution (pH < 7). As a salt of weak acid and strong base, CH₃COONa has a basic salt solution (pH > 7). Therefore, the CH₃COONa solution in water will be basic among the provided salts.
