Question

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

• A. $Al(CN)_3$
• B. $CH_3COOK$
• C. $FeCl_3$
• D. $Pb(CH_3COO)_2$

Answer 1

Answer: (B)

$CH_3COOK$

Answer 2

$CH _{3} COOK + H _{2} O \longrightarrow CH _{3} COOH + KOH$- Basic
$FeCl _{3}-$ Acidic solution
$Al ( CN )_{3}-$ Salt of weak acid and weak base
$Pb \left( CH _{3} COO \right)_{2}-$ Salt of weak acid and weak base
$CH _{3} COOK$ is salt of weak acid and strong base.
Thus, the solution of $CH _{3} COOK$ is basic.

So, the correct option is (B): $CH_3COOK$
