Nitrous oxide - N2O

What is Nitrous oxide?

Nitrous oxide is an oxide of nitrogen with a chemical formula N2O. This organic compound is colorless and non flammable at room temperature. It is also known as nitrous or laughing gas. Joseph Priestley was the first to identify nitrous oxide in the year 1772. This compound is insoluble in water and works as a powerful oxidizer at higher temperatures. It has a slightly sweet odor and appears as a colorless gas. When inhaled in small amount it causes mirth and euphoria. It is the world’s number one inhaled anesthetic as it works as a quick pain reliever. It can cause a narcotic effect at higher concentrations and lead to death by asphyxia.
