| 摘 要： | 本文将容量分析中常用的4大类反应(酸碱反应、氧化还原反应、沉淀反应、配位反应)用电子理论统一看成广义的酸碱反应,其相应广义酸碱的标准电极电位值,以标准氢电极为标准,可从实验和种计算方法得到。采用标准电极电位作为定量标度,将4类反应统一用电位滴定法来进行测定,讨论其反应进行的方向,反应进行的程度及筹当点时的电位值。

| Abstract: | This paper use electronic theroy regard four kinds of reaction which analytical chemistry often apply (acids--hases oxidation--reduction ptecipitate and complex formation reac- tion ) as generalized acids--bases reaction. Standard potential of these reactions can be obtained by experiments and calculations,to treat H--standard electrod as level,and .apply standard poten- tial as quantitative staff gauge. Four kinds of reaction can be unified measured by application po- tention etric titrations. This paper has discussed reaction direction reaction level and potential of e- quivalance point too. |
