Interpretation Introduction

Interpretation:

From the given compounds, the compounds that are more soluble in acidic solution compared to water have to be identified.

Concept introduction:

Acidic solution: Solution is considered to be acidic if anion (negatively charged species) is derived from strong acid and cation (positively charged species) derived from weak base.

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

Dissociation of salt forms strong conjugate base is more soluble in acidic compared to water.

An anion reacts with acid only if it is conjugate base of a weak acid.

Molar solubility is defined as amount of solute that can be dissolved in one litre of solution before it attains saturation.

Solubility of a compound is expressed as concentration of its ions in saturated solution.

The solubility product constant (${\text{K}}_{\text{sp}}$) is defined as the equilibrium between compound and its ions in an aqueous solution.
