1) When the anion of the solid is a good base, the solubility is greatly increased by acidifying the solution. This is true because acidifying the solution will protonate the anion, making it less basic and more soluble in water.
2. When the anion of the solid is a good acid, the solubility is greatly increased by acidifying the solution. This statement is false as acidifying the solution will protonate the anion, making it less soluble in water.
3. When the anion is not sufficiently basic, the ionic solid can be dissolved in a solution containing a ligand that forms stable complex ions with its cation. This is true as the formation of stable complex ions between the cation and a ligand can help to solubilize the ionic solid in water.
