... conjugate acid will be present. Conversely, the lower the [H ] (i.e., the higher the pH), the more the equilibrium shifts to the right, so the more conjugate base will be present. The exact ratio of base to acid depends on the pH and the pKa (Henderson-Hasselbalch Equation). Note that when pH = pKa, ...

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.
