Carl Wilhelm Scheele, a Swedish chemist, discovered chlorine in 1774 while experimenting with hydrochloric acid and manganese dioxide. The reaction between these two compounds produced a greenish-yellow gas, which Scheele named “dephlogisticated marine acid air.” However, Scheele mistakenly believed that the gas was a compound of oxygen and hydrochloric acid. It was not until 1810 that the English chemist Sir Humphry Davy proved that chlorine was an element. Davy’s work led to the widespread use of chlorine as a disinfectant and bleaching agent. Today, chlorine is used in a variety of industrial and household applications, including water purification, paper bleaching, and the production of plastics and other chemicals.
