Scheele heated manganese dioxide and hydrochloric acid and discovered this greenish, yellow gas. He did not, however, establish chlorine as an element. In 1810, chlorine was named and classified as an element by Humphrey Davy. It was named after the Greek word chloros, which means pale green. | Scheele heated manganese dioxide and hydrochloric acid and discovered this greenish, yellow gas.

Chlorine has also been used during World War I. It was first introduced as a weapon on April 22, 1915 at Ypres by the Germans. The results of this weapon were disastrous because gas makes had not yet been invented. But, some compounds of chlorine are more dangerous and have replaced chlorine gas on the battle field. They are phosgene, chloropicrin, Lewsite, and mustard gas. | Chlorine has also been used during World War I. It was first introduced as a weapon on April 22, 1915 at Ypres by the Germans.

Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite (manganese dioxide, MnO2) with hydrochloric acid (HCl, then known as muriatic acid). Scheele thought the resulting gas contained oxygen. Sir Humphry Davy proposed and confirmed chlorine to be an element in 1810, and he also named the element. | |||
