Description:

Iodine Powder Iodine Crystal or Granular, in the periodic table of chemical elements, is one of halogen group elements in the fifth periodic system_A group. In 1811, French pharmacist Kutwa first discovered iodine. Iodine Powder Iodine Crystal or Granular is purple-black crystal. It is easy to sublimate, easy to sublimate after sublimation.

Toxicity and corrosiveness. Iodine Powder Iodine Crystal or Granular can turn blue and purple when it comes to starch. It is mainly used in pharmaceuticals, dyes, iodine liquor, test paper and iodine compounds. Iodine Powder Iodine Crystal or Granular is one of the essential trace elements in human body. The total amount of iodine in healthy adults is 30 mg (20-50 mg). The national standard for adding iodine in salt is 20-30 mg/kg.

As the most famous China Iodine Powder Iodine Crystal or Granular supplier in China, Fengchen Group’s Product is well packed with the newest and the safest package.

Iodine Powder Iodine Crystal or Granular exists in nature in the form of water soluble. In nature, the content of iodine in most soils, rocks and water is very low, except for the higher content of iodine in seawater such as kelp, fish and shellfish (50-60 micrograms per liter of seawater).

Iodine Powder Iodine Crystal or Granular is rare in nature and ranks 47th in the crust. Except for the high content in seawater (50-60 micrograms per liter of seawater), the content in most soils, rocks and water is very low.

The iodine source in nature is mainly in the form of sodium iodate NaIO3, which exists in the saltpeter deposit of Chile. The iodine content in seawater is very low. However, some marine organisms (such as algae, kelp, etc.) have the ability to selectively absorb and enrich iodine, which is an important source of iodine.

Iodine Powder Iodine Crystal or Granular has a high vapor pressure and sublimates under mild heat. Pure iodine vapor is dark blue. If it contains air, it is purple red and has a irritating odor. Iodine Powder Iodine Crystal or Granular is soluble in many organic solvents, such as chloroform (CHCl3), carbon tetrachloride (CCl4). The solution of iodine in ethanol and ether is brown. Iodine forms purple solutions in solvents with low dielectric constants, such as carbon disulfide and carbon tetrachloride, in which iodine exists as a molecule. Although the solubility of iodine in water is very small, the solubility of iodine in potassium iodide KI or other iodide solutions increases significantly.
