Final answer:
The solubility of most substances depends on temperature and pressure. By adjusting the temperature or pressure, you can manipulate the solubility of a substance.
Step-by-step explanation:
The solubility of most substances depends strongly on temperature and, if a gas, on pressure as well. For example, Henry's law describes the relationship between the pressure and the solubility of a gas. By changing the temperature and pressure, you can manipulate the solubility of a substance. This can be done experimentally by adjusting the temperature or pressure in a controlled environment.
