Reactions of Oxygen
Oxygen does not react with acids or bases under normal conditions.
Reactions with water
Oxygen will not react with water.
Reactions with air
Oxygen gas does not react with itself or nitrogen under normal conditions. However the effect of ultraviolet light upon oxygen gas is to form the blue gas ozone, O3.
Reactions with halogens
Irradiation of a low pressure mixture of oxygen and fluorine gases will produce dioxygen difluoride.
