Oxygen oxidation

WebOxygen gas is used for oxy-acetylene welding and cutting of metals. A growing use is in the treatment of sewage and of effluent from industry. Biological role Oxygen first appeared in the Earth’s atmosphere around 2 billion years ago, accumulating from the photosynthesis of blue-green algae. WebOxygen can exhibit multiple oxidation states, but most commonly exhibits -2. The -1 oxidation state is present in peroxides and persulfates. Oxidation states +1, +2 are very rare for oxygen, and occur when combined with fluorine. Oxygen Compounds Oxygen is a highly reactive element.
