【摘要】 对第一终点ｐＨ小于３．７的两种一元弱酸混合酸溶液进行了半中和点法的可行性实验．结果表明，离解常数之比（Ｋａ２／Ｋａ１）大于２０倍时，参照半中和点法可以测量各组分酸含量，获得了较满意的结果．更多还原

【Abstract】 The probable experiment for the mixture of two weak monoacids that pH value was<3.7at the first terminal point was carried out byhalf neutralization point was carried outby half neutralization point method.Theresults showed that when the dissociation con-stants(Ka2/Ka1)was more than 20,the con-tent of each acid in the mixturc of two wedrk monoacids could be detected in the light of the half neutrlization point method.更多还原
