Q29 / 90 · JEE Main 2018 (08 Apr) · Chemistry

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

A
$Pb {({CH}_{3} COO)}_{2}$
B
$Al {(CN)}_{3}$
Correct answer
C
${CH}_{3} COOK$
D
${FeCl}_{3}$

Solution

Salt of $Pb {(OH)}_{2} + {CH}_{3} COOH$
Weak base Weak acid

Salt of $Al {(OH)}_{3} + HCN$
Weak base Weak acid

Salt of $Fe {(OH)}_{3} + HCl$
Weak base Strong acid

Hence, the nature of the solution is basic.

Hence, the correct answer is option: 'C'.
