How to make laughing gas in my school chemistry laboratory?

Nitrous oxide, N2O, is almost always prepared by heating ammonium nitrate (thermal decomposition) to 180 - 250 degree C. NH4NO3 = N2O + 2 H2O The temperature should be kept within 250 degree C by slow heating, as ammonium nitr... read more

The gas in the collection jar is your nitrous oxide or laughing gas, plus lesser amounts of other nitrogen oxides, including nitric oxide or nitrogen monoxide. Nitric oxide eventually is oxidized to nitrous oxide upon exposure to oxygen, although acid and base treatments are used to remove impurities for commercial-scale production of nitrous oxide. read more
