The two solutions of accurate pH calculation for HA-A standard buffer solution by the simplest form were introduced. Results from the two approaches agreed well with each other, and solution #2 was validated by examples. The calculation can improve the deduction ability of the learners and enhance their comprehensive understanding of pH computational formulas, and also be a useful supplement for current analytical chemistry textbooks.

Key words: Standard buffer solution, Accurate pH calculation, Activity coefficient, The simplest form
