उत्तर
Ammonia is a strong reducing agent. It is oxidised to nitrogen by removal of hydrogen, when it react with oxidizing agent.
(i) Reduction of chlorine
\[\ce{8NH3 (excess) + 3CI2 → N2 + 6NH4CI}\]
(ii) Reduction of copper (II) oxide
\[\ce{3CuO + 2NH3 ->[\Delta] 3Cu + 3H2O + N2}\]
Black Reddish brown
(iii) Reduction of lead (II) oxide
\[\ce{3PbO + 2Nh3 ->[\Delta] 3Pb + 3H2O + N2}\]
Yellow Grey
