Question

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

• A. $\text{C}{\text{H}}_{\text{3}}\text{COOK}$
• B. $\text{FeC}{\text{l}}_{\text{3}}$
• C. $\text{Pb(C}{\text{H}}_{\text{3}}\text{COOK}{\text{)}}_{\text{2}}$
• D. $\text{Al}{\left(\text{CN}\right)}_{\text{3}}$

Answer 1

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

$C{H}_{3}COOK+H_{2}O\to C{H}_{3}COOH+KOH$

On hydrolysis week acid which is acetic acid and strong base which is potassium hydroxide is formed.

So resulting solution will be alkaline in nature because a stronger base is formed and acid formed is weak.

Hence, option A is the correct answer.
