Hydrogen peroxide, also known as H2O2, is a chemical substance ubiquitous in nature. It is also a strong oxidant. It can be mixed with water in any proportion. It can also be soluble in alcohol and ether, but insoluble in benzene and petroleum ether. The pure liquid hydrogen peroxide is a transparent and pungent slurry, and the hydrogen peroxide system is most stable when the pH value is 3.5–4.5. Hydrogen peroxide is an important green chemical product, because its use will not cause any secondary pollution, and after oxidation, it decomposes into water and oxygen, which does not pollute the environment, so it is called “the cleanest” chemical product, which is widely used in medicine and food, paper industry, textile industry, chemical industry, environmental protection, electronic industry, and other fields.
