Report Abuse. Acidic Gases are those gases, which when dissolved in water, show acidic properties. CO2 when dissolved gives H2CO3, which is acidic, NO2 gives HNO3(Nitric Acid). SO2 gives Sulphurous Acid, SO3 gives Sulphuric Acid. There are plenty of such examples.
Nitrous oxide, commonly known as laughing gas, nitrous, nitro, or NOS is a chemical compound with the formula N 2O. It is an oxide of nitrogen. At room temperature, it is a colourless, non-flammable gas, with a slightly sweet odour and taste.It is used in surgery and dentistry for its anaesthetic and analgesic effects.t is also used as an oxidizer in rockets and in motor racing to increase the power output of engines. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen. Nitrous oxide gives rise to nitric oxide (NO) on reaction with oxygen atoms, and this NO in turn reacts with ozone.
