The calculation of hydrogen ion concentration is tightly associated with the conditions applied, and has been the keynote and difficulty part in study. A high degree univariate polynomial equation of hydrogen concentration was obtained by substituting the distribution fraction into the proton balance equation, and could be solved conveniently using MATLAB. Therefore, the calculation of the hydrogen concentration becomes easy as long as one can write the proton balance equation correctly. In such a way, students can better focus on learning the main knowledge of analytical chemistry.
