Question

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

Solution

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

`NH_4Cl_(aq) + NaNO_(2(aq)) -> N_(2(g)) -> + 2H_2O_((i)) + NaCl_((aq))`

NO and HNO3 are produced in small amounts. These are impurities that can be removed on passing nitrogen gas through aqueous sulphuric acid, containing potassium dichromate.

  Is there an error in this question or solution?
