Below its boiling point, it is a dark blue liquid, and it exists as a blue-black crystalline solid; as a gas, it is less stable than its more common allotrope.
Below its boiling point, it is a dark blue liquid, and it exists as a blue-black crystalline solid; as a gas, it is less stable than its more common allotrope. Discovered by Christian Friedrich Schönbein in 1840, this powerful oxidizing agent is used as a disinfectant and is produced industrially either using a mercury heat lamp or a process called cold discharge. For 10 points, name this compound formed by lightning or the action of solar ultraviolet light on diatomic oxygen, naturally present at about ten parts per million in its namesake layer of the stratosphere.
