Abstract: In this paper, based on the underlying logic, the general formula of the inverse function of the titration curve is derived based on the equilibrium expression and the basic quantitative relationship in the equilibrium system. The important information of the titration curve, including the stoichiometric point and the range of titration jump, is briefly discussed.
