<P> As in the case of Lugol 's iodine , the role of iodide in the solution is to increase the solubility of the elemental iodine , by turning it to the soluble triiodide anion I . However , since iodine has moderate solubility in ethanol , it is also assisted by this solvent directly . Lugol 's iodine , by contrast , has no alcohol , and has twice the mass of potassium iodide as of elemental iodine . Alcohol content in the tincture of iodine can be determined by the methods of Alcock , Roscoe - Schorlemmer and Thurston - Thurston . </P>
