利用溶度积常数判断转化反应的验证

Verification of judging coversion reaction with solubility product constant

本文通过溶度积常数判断BaSO4沉淀转化成BaCO3 沉淀的理论分析,并用实验验证了这个理论。结果表明:理论联系实践,实验检验理论是加深理解理论的重要环节。从而启发教师在上实验课时要把实验中可能出现的问题先交传学生,使学生由被动变为主动,提高学生分析问题和解决问题的能力。

The theory of judging BaSO_4 sedimentation transform to BaCO_3 sedimentation with solubility product constant was analysed,and it was verified by experiment.The result shows that integration of theory with practice and practice testing truth are important links for deep comprehension,and teachers had better to notice students the problems before experiment.It can make students initiative,and advance the abilities of resolving and analysing problems.
