Question

2. How is nitrogen prepared in the laboratory?
Write the chemical equations of the reactions involved​

Answer 1

chemical equation for nitrogen prepared in laboratory is NH4CL +NgNo2 - NH4NO2

Answer 2

Answer:

An aqueous solution of ammonium chloride is treated with sodium nitrite.

NH4Cl (aq ) + NaNO2 →N2(g) + 2H2O(l) + NaCl(aq)

NO and HNO 3

​

 are produced in small amounts. These are impurities that can be removed on passing nitrogen gas through aqueous sulphuric acid, containing potassium dichromate.
