The rate of reaction can be increased by using a catalyst, manganese(IV) oxide. When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off.]]> 2022-02-04 03:07:21 UTC https://padlet.com/aksharashiva7/Oxygen/wish/2028746714 Procedure: https://padlet.com/aksharashiva7/Oxygen/wish/2028753612 Some manganese dioxide and water is taken in a conical flask
Add some Hydrogen peroxide dropwise through the thistle
We can observe that o2 gas comes out of the delivery tube
Oxygen gas is collected by the downward displacement of water
