论文部分内容阅读
本刊根据读者的要求,从本辑始开辟《分析化学基础知识讲座》栏。对于该栏的内容、撰写的形式及其它,希望读者给本刊来信提出意见和建议,以便办好此栏。此栏第一篇文章“溶液平衡与容量分析的基础”,作者着眼于概括,从四种滴定(酸碱滴定、络合滴定、氰化还原滴定、沉淀滴定)的同一性出发,提出统一的平衡常数、副反应系数来处理上述滴定的四大平衡,得到等当点、指示剂变色点、滴定过程、变色敏锐程度的统一表达式,用不太复杂的数学形式,说明滴定过程,以便读者学习和掌握。本刊拟分四辑连载。
According to the readers’ requirements, we start with “Column of Analytical Chemistry Basics” from the beginning of this edition. For the contents of the column, the form of writing and other, I hope readers to comment on this letter and suggestions to facilitate this column. The first article in this column, “The Basis of Solution Equilibration and Capacity Analysis”, the author looks at the generalization of the four titrations (acid-base titration, complexation titration, cyanidation titration, precipitation titration) Equilibrium constant, side reaction coefficient to deal with the four balance of the titration, get equal points, indicator discoloration, titration, discoloration sensitivity of the unified expression, with less complicated mathematical form, titration process for readers Learn and master. This issue is divided into four series serial.
