... The degree of solubility depends on the difference between the polarity of solute and solvent ("like dissolves like"), the temperature, and, for solutions of gases, the pressure. A saturated solution contains all the solute that can be dissolved at a particular temperature. A supersaturated solution ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
