将两级离解常数均大于10~(-7),并离解常数之比Ka_1/Ka_2小于10~4倍的二元弱酸与强酸相混合时,推导出一个公式,并根据此公式提出各组分酸含量测定方法即标准曲线法.
A formula is deduced when a two-stage weak acid with a dissociation constant of more than 10 -7 and a dissociation constant Ka_1 / Ka_2 of less than 10 to 4 times are mixed with a strong acid. According to the formula, each component Determination of acid content of the standard curve method.
