Two Solutions of Accurate pH Calculation for HA-A Standard Buffer Solution by the Simplest Form

TANG Ming-Yu

Department of Materials, Metallurgy and Chemical Engineering, Yunnan Tin Vocational & Technical College, Gejiu 661000, Yunnan Province, P. R. China

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.
- Standard buffer solution,
- Accurate pH calculation,
- Activity coefficient,
- The simplest form
