The most commonly used (nominal) 5% solution consists of 5% iodine (I 2) and 10% potassium iodide (KI) mixed in distilled water and has a total iodine content of 126.4 mg/mL. The (nominal) 5% solution thus has a total iodine content of 6.32 mg per drop of 0.05 mL; the (nominal) 2% solution has 2.53 mg total iodine content per drop.
USP Tincture of Iodine is defined in the U.S. National Formulary (NF) as containing in each 100 mL, 1.8 to 2.2 grams of elemental iodine, and 2.1 to 2.6 grams of sodium iodide. Alcohol is 50 mL, and the balance is purified water. This "2% free iodine" solution has 0.08 mol/L of I 2, which provides about 1 mg of free iodine per 0.05 mL drop. The ...

Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. [4] The recommended strength solution contains 10% Povidone, with total iodine species equaling 10,000 ppm or 1% total titratable iodine. [4] It works by releasing iodine which results in the death of a range of microorganisms. [1]
In the alternative, iodine may be produced from iodophors, which contain iodine complexed with a solubilizing agent (the iodide ion may be thought of loosely as the iodophor in triiodide water solutions). Examples of such preparations include: [11] Tincture of iodine: iodine in ethanol, or iodine and sodium iodide in a mixture of ethanol and water.
Iodine chloride vapour tends to chlorinate phenol and salicyclic acid, since when iodine chloride undergoes homolytic dissociation, chlorine and iodine are produced and the former is more reactive. However, iodine chloride in tetrachloromethane solution results in iodination being the main reaction, since now heterolytic fission of the I–Cl ...
