... Solubility Equilibria: When the process of dissolution and precipitation are occurring at the same time and at the same rate, equilibrium is established. The equilibrium can be shown by an equation with two arrows or a double arrow: CaCl2 (s) Ca2+ (aq) + 2Cl- (aq) Note that the equation must be ba ...

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.
