Catalytic Decomposition of Hydrogen Peroxide
On the catalytic decomposition of hydrogen peroxide
The art of the world, in the change of matter, often depends on the wonder of catalysis. Now take the catalytic decomposition of hydrogen peroxide as the theory, study its rationality and observe its change.
Hydrogen peroxide, the molecular formula is\ (H_ {2} O_ {2}\), a colorless and strongly oxidizing liquid. Its nature is active, but under normal conditions, the decomposition is slow. To speed up its decomposition effect, you must borrow the power of the catalyst.
Catalysts can change the rate of chemical reactions, but their own quality and quantity are unchanged before and after the reaction. In the decomposition of hydrogen peroxide, common catalysts include manganese dioxide\ ((MnO_ {2}) \), copper sulfate\ ((CuSO_ {4}) \), etc.
When manganese dioxide is used as a catalyst, hydrogen peroxide meets and reacts immediately. The chemical formula is:\ (2H_ {2} O_ {2}\ stackrel {MnO_ {2 }}{=\!=\!=} 2H_ {2} O + O_ {2}\ uparrow\). Looking at the change, the hydrogen peroxide molecule on the surface of manganese dioxide gradually relaxes, the oxygen-oxygen bond breaks, and the hydrogen-oxygen bond rearranges, resulting in water and oxygen. Oxygen escapes, turning into bubbles and rising, while water remains in the vessel.
The catalysis of manganese dioxide is to reduce the activation energy of the reaction. For the activation energy, the molecule needs to exceed the energy barrier if it wants to react. Manganese dioxide provides a different reaction path for hydrogen peroxide molecules, so that the molecules can be phased and transformed without high energy.
Copper sulfate can also be used as a catalyst. Its catalytic principle is similar to that of manganese dioxide. Both interact with hydrogen peroxide molecules through their own structure and properties to promote their decomposition. Although the catalytic efficiency of copper sulfate may not be as strong as that of manganese dioxide, bubbles can also be seen to slow down, proving the progress of the reaction.
The catalytic decomposition of hydrogen peroxide is of great use in various fields of industry, life and scientific research. In industry, it can produce oxygen for combustion and oxidation; in life, it can be used for disinfection, and the new oxygen produced by its decomposition can be used to kill bacteria; above scientific research, it provides a good example for exploring the mechanism of chemical reactions.
View the catalytic decomposition of hydrogen peroxide, know the art of catalysis, and be the cardinal of chemical change. If you make good use of it, you can uncover the mystery of material change and create infinite benefits.
