Nitrogen

Chemical reactions




Reaction of nitrogen with air


Nitrogen gas does not react with air under normal conditions. If electric sparks are used, NO and NO2 is formed.


Reaction of nitrogen with acids


Nitrogen gas do not react with acids under normal conditions.


Reaction of nitrogen with bases


Nitrogen gas do not react with bases under normal conditions.


Reaction of nitrogen with halogens


Nitrogen gas do not react with halogens under normal conditions.


Reaction of nitrogen with hydrogen


Nitrogen can be brought to react with hydrogen. This is called the Haber process [4]

N2(g) + 3 H2(g)
400-500 °C
Fe catalyst

High pressure
2 NH3(g)


Reaction of nitrogen with metals/metal ions


When ingited, Ca reacts with nitrogen forming calcium nitride, Ca3N2.

3 Ca(s) + N2(g) Ca3N2(s)


When ingited, Mg reacts with nitrogen forming magnesium nitride, Mg3N2.

3 Mg(s) + N2(g) Mg3N2(s)


Reaction of nitrogen with water


Nitrogen gas does not react with water. It does, however, dissolve; 14 g/l at 20 °C and 1 atmosphere pressure.
