Interpretation Introduction

Interpretation: The barium salt out of $\text{Ba}{\left(\text{OH}\right)}_2$ ${\text{BaSO}}_{\text{4}}$ and ${\text{BaCO}}_{\text{3}}$ will dissolve in a strong acid such as $\text{HCl}$ has to be predicted.

Concept introduction: The solubility of insoluble salts containing anions (conjugate base of a weak acid) such as hydroxide, acetate, carbonate, phosphate and sulfide increases in the presence of strong acid than in pure water. Whereas the solubility of insoluble salts containing anions (conjugate base of a strong acid) such as chlorides decreases in the presence of strong acid than in the pure water.
