Titration curve plays a key role in quantitative chemical analysis with useful and easily acquirable information. A method was proposed in this paper to plot accurate titration curves by means of inverse or implicit functions. Inverse or implicit functions are easier than general ones in both derivation and programming implementation. Consequently, a large number of data points are readily obtained without much demand on either mathematical or programming knowledge, which results in highly accurate titration curves. The proposed method is effective for all sorts of chemical equilibrium systems, particularly for those that traditional methods are incapable of. With highly accurate titration curves, tasks are readily implemented, such as choosing indicators, assessing a titration scheme, calculating titration errors, and evaluating factors in titration. This research is a part of a project to introduce computer-based approaches into the curriculum of analytical chemistry.
