Nitrogen — Chemistry Keypoint

Nitrogen

by

NITROGEN: It occurs mainly as a free element in the air making up about 78% volume of the atmosphere.

Laboratory Preparation of Nitrogen

It is prepared by the decomposition of ammonium dioxinitrate (iii). NB: We combine NaNO 2(aq) AND NH4CL(aq) for the decomposition since direct heating of NH4NO2 is very dangerous.

NaNO2(aq) + NH4CL(aq)  →   NH4NO2(aq) + NaCL(aq)

NH4NO2(aq)  →  N2(g) + 2H2O(L)

It can also be obtained from the air.

Industrially, it is obtained in the fractional distillation of air.
