Pure nitrogen is prepared in the laboratory by heating a mixture of
A.
$$N{H_4}OH + NaCl$$
B.
$$N{H_4}N{O_3} + NaCl$$
C.
$$N{H_4}Cl + NaOH$$
D.
$$N{H_4}Cl + NaN{O_2}$$
Answer :
$$N{H_4}Cl + NaN{O_2}$$
Solution :
In the laboratory dinitrogen is prepared by heating an aqueous solution containing an equivalent amount of ammonium chloride and sodium nitrite.
$$N{H_4}Cl\left( {aq} \right) + NaN{O_2}\left( {aq} \right)$$ \[\xrightarrow{\text{Heat}}{{N}_{2}}\left( g \right)+2{{H}_{2}}O\left( l \right)+NaCl\]
