实验室制备氧气催化剂的选用及用量探讨

On the Selection and the Quantity of Preparing Oxygen Catalyst in the Lab

通过这次实验,认识二氧化锰作为催化剂,在实验室制备氧气中的优越性;并对二氧化锰与氯酸钾以何种比例混合使产率最好进行初步的探讨。

The experiment shows the advantage of the managanese dioxide as catalyst in preparing oxygenin the lab. A discussion is also made to find out what is the right mixing proportion ofmanaganese dioxide to potassium chlorate to produce most.
