Polar solutes will dissolve better in polar solvents, and non-polar solutes will dissolve better in non-polar solvents. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute. However, the process of solubility is unique, and the rate at which it dissolves is not factored into the equation. The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution.
