A Unified Equation Derived from the Charge Balance Equation for Constructing Acid-Base Titration Curve and Calculating Endpoint Error
Abstract:
Starting from the Charge Balance Equation (CBE), this paper derives the inverse function V= g([H+]) for the titration curve, and directly employs this inverse function to calculate the endpoint error. Based on the characteristics of the CBE formula, the CBE forms of all acid-base systems are unified, and the straightforward correlation between the titration curve and the endpoint error provides learners with a new perspective to understand the connotation of acid-base equilibrium.
