Terrestrial abundance and distribution of Di oxygen (O2)

 * Di oxygen is the most abundant element in the earths crust(50%).It is found both in free state and combined state.In free state it is found in atmosphere (21% by volume and 23.2% by weight).In combined state,it is found in the form of water,carbonates and oxides of metals.

Isolation of Di oxygen :Pure Di oxygen can be obtained by two methods
1. From air  : Di oxygen can be isolated from air by its liquefaction followed by fractional distillation. 2. From water :water containing small amount of acid or alkali,on electrolysis liberates Di oxygen at anode and Di hydrogen at cathode.

Atomic and physical properties :
1.It is color less,odorless and tasteless gas. 2.It is slightly soluble in water. 3.Its melting point is 54.4 k and boiling point is 90.2 k.       4.When liquefied, it forms pale blue liquid. 5.On solidification, it forms bluish white solid. 6.It is supporter of combustion.
