Chemical And Ionic Equilibrium Result Question 10

Answer:

Correct Answer: 10. ( b )

Solution:

10. Among the given salts

$\mathrm{FeCl} _3$ is acidic in nature i.e., have acidic solution as it is the salt of weak base and strong acid.

$\mathbf{A l}(\mathrm{CN}) _3$ and $\mathbf{P b}\left(\mathbf{C H} _3 \mathbf{C O O}\right) _2$ are the salts of weak acid and weak base.

$\mathrm{CH} _3 \mathrm{COOK}$ is the salt of strong base and weak acid.

Hence, the solution of $\mathrm{CH} _3 \mathrm{COOK}$ will be most basic because of the following reaction.

$CH_3COOk + H_2O \rightleftharpoons \underset{\text{Weak acid}}{CH_3COOH} + \underset{\text{Strong base}}{KOH} $
