Manganese Dioxide Hydrogen Peroxide Reaction
The Reaction of Manganese Dioxide and Hydrogen Peroxide
In the past, school children were used to learning the order and studying the wonders of chemistry. One day, the teacher placed manganese dioxide and hydrogen peroxide in front of him, so that all the children could watch the change.
The schoolchildren gathered around and looked at it. There is a bottle containing hydrogen peroxide, which is clear in color and pure in quality, and a little manganese dioxide, which is black and light in color. The teacher poured manganese dioxide into the hydrogen peroxide bottle, and if there was a dragon in the bottle, the air would bubble up, like the upsurge of boiling soup, and the heat would rise accordingly.
All the children were startled, or some were dumbfounded, or some were whispering. The teacher said: "This is the reaction between manganese dioxide and hydrogen peroxide. Manganese dioxide is a catalyst. Although its own quality and quantity remain unchanged before and after the reaction, it can promote the rapid decomposition of hydrogen peroxide. Hydrogen peroxide decomposes to produce water and oxygen, and this bubble is also oxygen. "
When the school children heard it, they began to understand the magic of chemistry, and they understood the principles of reaction. Since then, the children have become more diligent, and they are good at studying the mystery of chemistry.
