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

Text Solution

Verified by Experts

Nitrogen is prepared in the laboratory by heating an equimolar aqueous solution of ammonium chloride and sodium nitrite. The ammonium nitrite formed as a result of double decompositon reaction, being unstable decomposes to form dinitrogen gas.
`NH_(4)Cl (aq) + NaNO_(2)(aq) rarr NH_(4)NO_(2)(aq) + NaCl (aq)`
`underset("Amm. nitrite")(NH_(4)NO_(2)(aq)) overset("Heat")rarr underset("Dinitrogen")(N_(2)(g)) + 2H_(2)O(l)`
