Manganese Dioxide Hydrogen Peroxide Experiment
Manganese dioxide and hydrogen peroxide experiment
Pour an appropriate amount of hydrogen peroxide solution into a clean container, its shape is clear and placed in a stable place.
Take a little manganese dioxide powder, this powder is black and delicate like dust. Sprinkle it gently into the hydrogen peroxide solution.
In an instant, the solution seems to have a wonderful change. A large number of bubbles gushed out rapidly, like a flood dragon exhaling air at the bottom of the water, tumbling and leaping. This is because manganese dioxide acts as a catalyst to accelerate the decomposition of hydrogen peroxide, generating water and oxygen.
The wooden strip with Mars was placed at the mouth of the container, and the wooden strip reignited, and the flame was bright and leaping, which proved that the generated gas was oxygen.
Looking at this experiment, we can see the magic of chemical reactions. Although manganese dioxide does not participate in the chemical decomposition of the substance, it greatly accelerates the reaction rate in the decomposition of hydrogen peroxide, which is very useful. This experiment is also one of the ways to explore the mysteries of chemical change, so that our generation has a deeper understanding of the interaction between substances.
