What is the largest oxide of oxygen content?
[Oxygen content of the largest oxide] is hydrogen peroxide, the formula: H2O2; oxygen content of the mass fraction of 94.1%.
[Hydrogen peroxide] pure hydrogen peroxide is a light blue viscous liquid, can be any proportion of mixed with water, is a strong oxidant, aqueous solution commonly known as hydrogen peroxide, colorless transparent liquid. The aqueous solution for medical wound disinfection and environmental disinfection and food disinfection. Under normal circumstances will be broken down into water and oxygen, but the decomposition rate is extremely slow, speed up its reaction rate is to join the catalyst - manganese dioxide or with short-wave radiation.
H2O water, H2O2 hydrogen peroxide is not, it is peroxide, the highest oxide is water H2O
