How can solubility be changed?

The variables that affect the substance's solubility are the

Since naphthalene is a non-polar compound and water is more polar than kerosene, sodium chloride is highly soluble in water but very poorly soluble in kerosene. This difference in solubility can be attributed to the higher polarity of water in comparison to kerosene.

This principle is used to make supersaturated solutions impure substance by raising the temperature and then filtering at a higher temperature, leaving the undissolved substance in residue. By cooling the filtrate, we obtain crystals of purified substance, such as sugar prepared from sugar cane juice. Generally speaking, increasing temperature increases solubility.

The solubility of silver chloride in sodium carbonate extract is very low; however, it dissolves in solution when ammonium hydroxide is added.

Solubility can be changed by altering factors such as temperature, pressure, and the nature of the solute and solvent.
