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

$Al(CN)_{3}$

$CH_{3}COOK$

$FeCl_{3}$

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

Option B

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)
