GENERAL PROPERTIES OF OXYGEN

Oxygen is the most abundant element on earth. It is prepared in the laboratory by catalytic decomposition of Potassium trioxochlorate(V) or hydrogen peroxide. Industrially, it is prepared by the liquefaction of air followed by fractional distillation of liquefied air.

Oxygen, being strongly electronegative, is chemically very reactive. It reacts with most metals to form basic oxides which are ionic, they also reacts with most non- metals to form acidic oxides which are covalent molecules and they reacts with hydrocarbons,  fuels[to form CO2 and H2O. It rekindles a glowing splint to indicate its presence in any place.

The oxides of oxygen can be classified into basic, acidic, amphoteric and neutral oxides. Peroxide is prepared by the action of a dilute acid on the peroxides of certain metals. It is a strong oxidizing agent. However, in the presence of more powerful oxidizing agents, ozone, O3, is an unstable allotrope of oxygen. The ozone layer in the atmosphere acts as a protective shield by preventing too much ultra-violet radiation from falling on earth and harming living organism.
