What chemical compound has the formula H2O2?
Hydrogen peroxide is a chemical compound with the formula H2O2. This agent is described as a colorless liquid, a bit more sticky than water. Anyway, it's usually held at households as an aqueous solution. As it is a compound with an oxygen–oxygen single bond, it's the simplest peroxide. Hydrogen peroxide is widely used in our everyday life, as it is a strong oxidizer, disinfectant and bleaching agent. It's also used in rocketry as a propellant, but only in a very concentrated form.
The chemical formula of hydrogen peroxide has a lot of in common with that of water. It's often called "water but with one more oxygen atom". Anyway, it differs from water a lot, even if the appearance of the two compounds is similar. Unlike water, pure hydrogen peroxide explodes if heated to boiling, which is very dangerous.
