Question

Which of the following salts form the most basic aqueous solution?

• A. $Pb(C{H}_{3}COO{)}_2$
• B. $Al(CN{)}_3$
• C. $C{H}_{3}COOK$
• D. $FeC{l}_3$

Answer 1

The correct option is C $C{H}_{3}COOK$

Any salt formed by a weak acid is more basic in aqueous solution.When $C{H}_{3}COOK$ is dissolved in an aqueous solution it gives $C{H}_{3}COOH$ and $KOH$. Acetic acid is a weak acid so, $C{H}_{3}COOK$ will be more basic in aqueous solution.
