摘要
通过对醋酸水溶液标准平衡常数实验测定方法的研究及实验数据的分析,得出不同浓度的醋酸标准系列浓度越高,pH 实测值才会更接近理论值,实验得到的标准平衡常数Kaθ(HAc)才更接近真实值。
It is concluded that the higher the concentration of acetic acid standard series ,while the higher the pH value being closer to the theoretical value by the study of the experimental method for the standard equilibrium constant of acetic acid aqueous solution and the analysis of experimental data. Then the standard equilibrium constant obtained by the experiment is closer to the true value.
