NTA AbhyasNTA Abhyas 2022 Report Error

$Pb\left(\right.CH_{3}COO\left(\left.\right)_{2}$

$Al\left(\right.CN\left(\left.\right)_{3}$

$CH_{3}COOK$

$FeCl_{3}$

Solution:

$CH_{3}COOK$ is most basic among the given salts as its aqueous solution contains strong base KOH and weak acid $CH_{3}COOH$ so $OH^{-}$ concentration is more than $H^{+}$ .
