Chapter 17, Problem 17.14QP

Interpretation Introduction

Interpretation:

From the given acids, the salt which get affected by solubility when it dissolves in $\text{HCl}$ has to be identified.

Concept introduction:

Acid dissociation constant ${\text{K}}_{\text{a}}$ is defined as measure of acid strength in a given solution.

In an aqueous solution,

$\begin{array}{l}\text{HA}\text{+}{\text{H}}_{\text{2}}\text{O}\stackrel{}{\rightleftharpoons }{\text{A}}^{\text{-}}\text{+}{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\\ \\ {\text{K}}_{\text{a}}\text{=}\frac{{\text{[A}}^{\text{-}}{\text{][H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}}{{\text{[HA][H}}_{\text{2}}\text{O]}}\end{array}$
