Uses

Colorless, odorless, tasteless gasThe common reaction in which it unites with another substance is called oxidation

DiscoveryOxygen was produced by many chemists prior to its discovery in 1774, but they failed to recognize it as a distinct element. Joseph Priestley and Carl Wilhelm Scheele both independently discovered oxygen. Priestly is usually given credit for the discovery though. They were both able to produce oxygen by heating mercuric oxide (HgO). The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids

From the greek words oxys and genes, which together mean "acid forming."

Oxygen is utilized in medicine in the treatment of respiratory diseases and is mixed with other gases for respiration in submarines, high-flying aircraft, and spacecraft. Also, the chemical and the iron and steel industries. A growing use is in the treatment of sewage and of effluent from industry.
