Some methods are:
- increasing the temperature
- stirring
- if the solute is a solid, reducing the grain sizes
- increasing the pressure
Solubility can be increased in solvent and by adding more solute.
The vast majority of compounds increase in solubility as the temperature increases.
When the pressure increase the solubility increase.
Increasing the pressure and decreasing the temperature the solubility increase.
The solubility of gases in liquids increase when the pressure increase.
When the temperature increase the solubility also increase.
If the pressure of the gas increase, the solubility in a liquid increase.
The movement of the particles in the solute and between solute and solvent are amplified at higher temperature and the solubility increase.
Increase in temprature brings about increase in the rate of reaction and this does affect d solubility of the subtance
At high pressure the solubility increase.
You can increase the solubility of a gaseous solute in a solvent by increasing the pressure of the system. Henry's Law states that the solubility of a gas is directly proportional to its partial pressure, so increasing the pressure will result in more gas dissolving in the solvent. Additionally, lowering the temperature also generally increases the solubility of gases in liquids.
The solubility of gases increase at low temperature.
