1)

Which of the following salts is the most basic in aqueous solution?


A) $Al(CN)_{3}$

B) $CH_{3}COOK$

C) $FeCl_{3}$

D) $Pb(CH_{3}COO)_{2}$

Answer:

Option B

Explanation:

Among the give salts

FeCl3 is acidic in nature i.e., have an acidic solution as it is the salt of a weak base and strong acid.

Al(CN)3 and Pb(CH3COO)2 are the salts of a weak acid and weak base.

CH3COOK is the salt of a strong base and weak acid.

Hence, the solution of CH3COOK will be most basic because of the following reaction.

CH3COOK  +   H2O     $\rightleftharpoons$       CH3COOH (Weak acid)  +  KOH  (Strong base)
