Chapter 15, Problem 78AE

Interpretation Introduction

Interpretation: Two salts, namely $\text{AgX}$ and $\text{AgY}$, having similar values of $K_{\text{sp}}$ are given. The $K_{\text{a}}$ for $\text{HX}$ is given to be much greater than $K_{\text{a}}$ for $\text{HY}$. The salt that will be more soluble in an acidic solution is to be stated.

Concept introduction: According to the general rule, if the anion ${\text{X}}^{-}$, in $\text{HX}$, is an effective base, then the salt $\text{MX}$ formed will be more soluble in a given acidic solution
