The information of concentration of product and reactant at equilibrium is given by acid or base equilibrium constant give.
Equilibrium constant tells about the relative ratio of the concentration of product and reactant at the equilibrium.
As the name acid or base equilibrium constant suggested that they also give the relation between the concentration of the reactants and products at equilibrium.
HA + H₂O ⇄ A⁻ + H₃O⁺
Acid equilibrium constant is denoted as Ka and for the above reaction at equilibrium it can be written as:
Ka = [H⁺] [A⁻] / [HA]
Similarly, base equilibrium constant Kb is also define as the ratio of the concentration of product to the concentration of reactant.
Hence, an acid or base equilibrium constant give information about concentration.
