Is a iodine a metal
WebPovidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone) and triiodide (I 3 −).. It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.Its stability in solution is much greater than that of tincture of iodine or Lugol's solution.. Free iodine, slowly liberated from the povidone-iodine … WebTriiodide is a model system in photochemistry. Its reaction mechanism has been studied in gas phase, solution and the solid state. In gas phase, the reaction proceeds in multiple pathways that include iodine molecule, metastable ions and iodine radicals as photoproducts, which are formed by two-body and three-body dissociation.
