Question

Identify the substance whose 0.1 M solution is basic? (A) Ammonium chloride (B) Ammonium acetate (C) Ammonium sulphate (D) Sodium acetate

Tardigrade Admin · Accepted Answer

Sodium acetate is a salt of strong base

(N a O H)

and weak acid

(C H_{3} COO H)

.
In aqueous solution it gets hydrolysed as

C H_{3} COON a + H_{2} O \to C H_{3} COO H + N a O H

or

C H_{3} CO O^{-} + N a^{+} + H_{2} O \to C H_{3} COO H

+ N a^{+} + O H^{-}

or

C H_{3} CO O^{-} + H_{2} O \to C H_{3} COO H + O H^{-}

Because of the excess of

[O H^{-}]

in aqueous solution, its solution is basic in nature.
Aqueous solution of salt of strong acid and weak base is acidic and that of strong
acid and strong base is neutral.
