Answer 1

Answer #1

compound	Does solubility change with pH	highest solubility
compound	Does solubility change with pH	pH = 6	pH = 7	pH = 9
AgCl	no
Ca(OH)₂	yes	correct
Ca₃(PO₄)₂	yes	correct

Explanation

Insoluble compounds made from conjugate bases of weak acids have higher solubility in acidic solution because the conjugate base forms back the weak acid by combining with hydrogen ions (H⁺).
