Flexi Says: Solubility is the amount of solute that can dissolve in a given amount of solvent at a given temperature. Temperature affects the solubility of solutes in all three states. Pressure also affects the solubility of gases. The rate of dissolving is the rate at which a solute dissolves in a solvent. The rate of dissolving of a solute in a solvent is faster when the solute and solvent are stirred, the solvent is warmer, or the solute consists of smaller particles with more surface area.
