Answer» Solution :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)` |
