摘要
从反映酸碱反应中质子转移的最严密的数量关系———质子条件 (PBE)出发 ,结合定量分析计算所允许的误差要求 ,对滴定弱酸碱时的pH突跃等问题进行了研究 ,导出了具体的计算公式 。
From PBE, which reflects the most rigorous quantitative relation of the displacement of the protons in acid and alkaline reaction, the essay combines the error requirements that the quantitative analysis allows, studies the problem of sudden change of pH in weak acid and alkaline titration, reaches the specific calculational formula and offers a solution for this kind of problem.
