本文评述了克当量和当量浓度在量纲上存在着难以克服的缺陷;讨论了废除当量浓度,采用物质的量浓度的优越性。对所谓“等物质的量反应规则”及其计算公式进行了剖析,说明其不宜作为滴定分析计算的依据。 本文指出由质量守恒定律导出下列公式,是采用物质的量浓度后滴定分析计算的基础: 对于反应 aA+tT=pP+qQ
In this paper, we review the inequality deficiencies of gram equivalent and equivalent concentrations in terms of dimensions. We discuss the advantages of abolishing the equivalent concentration and using the concentration of the substance. The so-called “quantitative reaction rules of substances” and its formula were analyzed, indicating that it should not be used as a basis for the titration analysis. This paper points out that the following formula derived by the law of conservation of mass is the basis for post titration analysis using the substance concentration: For the reaction aA + tT = pP + qQ
