把酸、还原剂和络合物看作粒子给予体,它们分别给出的是质子,电子和配位体。碱、氧化剂和金属离子看作粒子接受体。运用给予体和接受体共轭对之间的粒子转移概念讨论共轭酸碱、氧化还原和络合平衡,归纳三者在滴定过程中滴定曲线的统一计算式和准确滴定的判据,以及滴定误差的计算。便于学生对三类平衡的学习和理解。
The acids, reducing agents and complexes are considered as particle donors, which respectively give protons, electrons and ligands. Alkalis, oxidants and metal ions are considered as particle acceptors. The conceptions of conjugate acid-base, redox and complexation are discussed by using the concept of particle transfer between donor and acceptor conjugate pair. The unified formulas of titration curve and the criterion for accurate titration of the three titration curves are summarized, and the titration Error calculation. It is easy for students to learn and understand three types of balance.
