Ozone, known by the IUPAC surname of trioxygen, is an not natural gas link of atmosphere. Its lack has actually been linked to environmental difficulties due it is the key constituent that ozone shield.

You are watching: What is the formula for ozone

Formula and structure: The ozone chemistry formula is O3 and also its molar mass is 48.00 g mol-1. The molecule is developed by three oxygen atom in a structure highly resonant v 1 twin bond and also 1 solitary bond and additional 2 partial charges: a an unfavorable and a positive. The usual representation of ozone molecule shows it as a "V" framework with an angle of 116.78º between the central carbon atoms and the other two carbons. Its chemical structure have the right to be created as below, in the usual representations offered for essential molecules.


Occurrence: Ozone is large found in environment where is created from molecular oxygen O2 and also UV light or electrical discharges. The ozone forms the ozone layer, a gas layer the is 10-50 km over the Earth"s surface.

Preparation: Ozone is mostly discovered in nature, where is developed through a reaction known as Chapman cycle and it consists in the development of the ozone from molecular oxygen and UV light. In chemistry laboratories it is created by passing air between two electrodes (that have the same role which UV light).

Physical properties: Ozone is a pale blue come colorless gas v a pungent or sharp odor. Its density is 2.144 g mL-1. Its melting suggest is -192.2 ºC and its boiling point is -112 ºC. Ozone is no soluble in water however it is dissolve in carbon tetrachloride and sulfuric acid.

Chemical properties: Ozone is well-known by the oxidizing power, which stays like among the many powerful. It can oxidize all metals except gold and also platinum (reaction I); nitric oxide (reaction II) and additionally nitric oxide (III); sulfides link (IV):

Cu + O3 → CuO + O2 (I)

NO + O3 → NO2 + O2 (II)

NO2 + O3 → no 3 + O2 (III)

PbS + 4 O3 → PbSO4 + 4 O2 (IV)

Ozone is diamagnetic and also unstable, thus it decomposes conveniently to oxygen:

2 O3 → 3O2

Use: Ozone is mainly used in sector to promote many oxidations such as defined above. The is also used for burning reactions and in countless combustible gases. Ozone is many useful in the water treatment. This is crucial component of our setting due the ozone great protects against the UV light.

Health effects / safety hazards: Ozone can cause skin and also eyes irritation. That is fatal by inhalation and ingestion and also can also cause genetic defects. Ozone is really toxic come aquatic life. That is a solid oxidant, so the it deserve to or intensifies fire and also can reaction with countless chemical substances.
