摘要：氨基甲酸铵分解平衡实验是一个经典的物理化学实验。该实验装置设计思路清晰,易于操作。但我们在长期教学实践中,我们发现由于学生操作和现存实验装置都存在一定问题,实验操作经常显得费时费力,实验误差增大。本文结合我们的教学与管理经验谈一点体会,并提出一些建议。
The experiment of testing the equilibrium constant of decomposition of NH4COONH2 is a classical physical chemistry experiment.The equipment of this experiment is simple and convenient and the design idea is clear.But there are some problems in the teaching experience due to the wrong operation and the defects in the equipment.Time and energy are wasted in the experiment and deviation appears.Experience achieved in teaching and management is expounded and suggestion is given here.
