Notes on hydrogen peroxide
Concepts Used:
Hydrogen Peroxide
Hydrogen peroxide is a chemical element including hydrogen and oxygen. Anhydrous hydrogen peroxide is a colorless, sugary liquid that breaks down quickly into oxygen and water. The chemical formula for hydrogen peroxide [H2O2] is H—O—O—H, here, each dash represents a single covalent link. Especially, each bond has a pair of mutual electrons, one from each of the atoms at the bond’s ends. The polar bonds are H—O bonds, but this is not the polar one - O—O bonds.
Physical Properties:
- In its pure state, hydrogen peroxide is an entirely transparent colorless liquid with a nitric acid-like odor.
- The consistency of hydrogen peroxide is far better than that of water. It has a density of about 40% that of water.
Chemical Properties:
- It dissolves in water, which after getting mixed with water produces a homogenous solution.
- Naturally acidic in nature.
- The oxidizing agent H2O2 is quite powerful. As a derivative, it gives up one oxygen atom and forms water.
