图解法在分析化学教学中的应用
Application of Graphical Method in Analytical Chemistry Teaching
【摘要】 简要阐述了当前分析化学教学中存在的主要问题,提出了利用图解法解决优势分布、络合滴定中终点误差的计算、氧化还原滴定的相关计算、质子平衡式的书写,以及沉淀溶解度的计算等问题的对策。教学实践证明图解法具有概括、简洁和直观的优点,在分析化学教学中是一种行之有效的方法。
【Abstract】 In the present paper,the authors briefly discussed the main problems in current analytical chemistry teaching.And the authors proposed graphical method to solve many problems such as predominance distribution,resolution of end point error in complexometric titration,related calculations in oxidation-reduction titration,writing of proton balance equation,and calculation of precipitate solubility.Teaching practices revealed that graphical method had the advantages of generality,intuitiveness and brevity and it was an effective means in analytical chemistry teaching.
