Tarihi
Iodine was discovered by French chemist Bernard Courtois in 1811.
He treated the liquor obtained from the extraction of kelp, with sulfuric acid to produce a vapour with a violet color.
In 1812, Joseph Louis Gay-Lussac demonstrated that iodine was an element and its chemical relationship to chlorine.
