Ozone, recognized by the IUPAC name of trioxygen, is an not natural gas compound of atmosphere. The lack has been connected to environmental difficulties due that is the key constituent that ozone shield.

You are watching: What is the molecular formula for ozone


Formula and also structure: The ozone chemistry formula is O3 and also its molar mass is 48.00 g mol-1. The molecule is created by 3 oxygen atom in a structure highly resonant with 1 dual bond and 1 single bond and added 2 partial charges: a negative and a positive. The usual representation of ozone molecule shows it as a "V" framework with an angle of 116.78º in between the main carbon atoms and also the other two carbons. Its chemical structure deserve to be written as below, in the typical representations offered for necessary molecules.

Occurrence: Ozone is large found in setting where is created from molecule oxygen O2 and also UV light or electric discharges. The ozone develops the ozone layer, a gas layer the is 10-50 km above the Earth"s surface.

Preparation: Ozone is mostly discovered in nature, where is produced through a reaction recognized as Chapman cycle and it consists in the formation of the ozone from molecule oxygen and UV light. In chemistry laboratories it is developed by pass 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 spicy odor. Its thickness is 2.144 g mL-1. Its melting allude is -192.2 ºC and its boiling point is -112 ºC. Ozone is not soluble in water yet it is dissolve in carbon tetrachloride and also sulfuric acid.

Chemical properties: Ozone is known by the oxidizing power, which remains like one of the many powerful. It have the right to oxidize every metals except gold and platinum (reaction I); nitric oxide (reaction II) and also nitric oxide (III); sulfides compounds (IV):

Cu + O3 → CuO + O2 (I)

NO + O3 → NO2 + O2 (II)

NO2 + O3 → three + O2 (III)

PbS + 4 O3 → PbSO4 + 4 O2 (IV)

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

2 O3 → 3O2

Use: Ozone is mostly used in market to promote countless oxidations together as explained above. It is also used for combustion reactions and in plenty of combustible gases. Ozone is many useful in the water treatment. This is vital component the our atmosphere due the ozone layer protects against the UV light.

Health results / safety and security hazards: Ozone can reason skin and also eyes irritation. It is fatal by inhalation and also ingestion and can likewise cause hereditary defects. Ozone is very toxic come aquatic life. That is a solid oxidant, so the it deserve to or aggravates fire and also can react with numerous chemical substances.
