Chapter 5, Problem 116SAE

Interpretation Introduction

Interpretation:

The list of the compounds containing weak acid, weak base and a salt needs to be determined from the given list of species.

Concept introduction:

A weak acid is a compound or solute which does not completely dissociates or ionizes in solution. This acid partially dissociates to give proton or hydronium ion in the solution.

The concentration of proton increases with an increase in the volume of solution such as ${\text{CH}}_{\text{3}}\text{COOH}$.

A weak base is a compound or solute which doesn’t get completely dissociated or ionized in solution. This base partially dissociates to give hydroxide ion in the solution.

They dissociate up to 10 % or get partially ionizes in water and concentration of hydroxide increases with an increase in the volume of solution such as ${\text{NH}}_{\text{4}}\text{OH}$.

Salt is a non-electrolyte produced from the combination of either weak acid and strong base or strong acid and weak base or weak acid and weak base.

It does not dissociate or ionizes in the solution.
