Physical and chemical properties: Purple-black scales or platelets with metallic luster.
It is brittle and the steam is purple. Has a special irritating smell.
Solubility is slightly soluble in water, and the solubility increases with increasing temperature; hardly soluble in sulfuric acid; easily soluble in organic solvents; iodine is also easily soluble in chloride and bromide; more soluble in iodide solution; soluble in sulfur, Ammonium and alkali metal iodides, aluminum, tin, titanium and other metal iodides.
Iodine, non-metallic element, element symbol I, periodic table element 53, in the fifth period of the periodic table, group 7, one of the halogen elements.
Elemental iodine was first discovered in 1811 by the French apothecary Koutwah. Elemental iodine is purplish black crystal, easy to sublimate, sublimate easy to condense, toxic and corrosive. Elemental iodine turns bluish-purple when it meets starch.
Iodine is mostly used in the production of organoiodide compounds, with 15% remaining in elemental form, 15% used as potassium iodide, and the last 15% being made into other inorganic iodine compounds. The main uses of iodine compounds include catalysts, animal food additives, stabilizers, dyes, colorants, pigments, pharmaceuticals, hygiene (iodine) and photography. Niche uses of iodine compounds include de-fogging, cloud seeding, and use in analytical chemistry.
