Final answer:
In an acidic solution, compounds that can ionize more and create more hydronium ions (H+) will be more soluble than in pure water.
Step-by-step explanation:
In an acidic solution, compounds that can ionize and create more hydronium ions (H+) will be more soluble than in pure water. This is because the higher concentration of hydronium ions in an acidic solution suppresses the formation of hydroxide ions (OH-), shifting the equilibrium towards the formation of more dissolved compound.
For example, if we compare the solubility of salt A and salt B, and salt A can readily ionize to produce more hydronium ions, it will show greater solubility in an acidic solution than in pure water.
The solubility of a compound in acidic solution will vary depending on its chemical properties and the strength of the acid present.
