Question

Which one of the following salts gives an acidic solution in water? (A)  CH3COONa  (B)  NH4Cl  (C)  NaCl  (D)  CH3COONH4

Tardigrade Admin · Accepted Answer

Salt formed between strong acid and weak base, solution of such type of salt is acidic in nature.

N H_{4} Cl

is an example of such type of salt.

N H_{4}^{+} + C l^{-} + H_{2} O ⇌ N H_{4} O H + H^{+} + C l^{-}

since,

C l^{-}

common on both sides.

N H_{4}^{+} + H_{2} O \to N H_{4} O H + H^{+}
