Study on Experiment Teaching of Dechlorination from Rhodochrosite

In order to ignite the students' interest in learning of inorganic experiment,and develop the students' subjective initiative to learn,the content of inorganic experimental teaching has been enriched and perfected.The rhodochrosite dechlorination study has been designed exploratory experiment and introduced into inorganic experiment teaching,the difficulty of experiment has been enhanced suitably,the student was required to grope for conditions according to their study.While considering the length and the complexity of the experiment,the students were grouped,and allocated time and work by themselves to complete the experiment.Through teaching practice,it is found that the design experiment not only improves the students' experimental literacy and research ability,but also enhances students' cooperative consciousness and cooperation ability.
