Put the iodine tincture in a shallow glass dish; let it evaporate at room temperature; what's left behind is a thin film of crystalline iodine that you can scrape off - note: iodine like chlorine is very reactive; that's why it's used as a germicide - were you to put a candle under the dish you would see the iodine sublimate (go directly from a solid to a brownish gas). Iodine does not come in a powder form, but you can get USP (United Stated Pharmaceutical Grade) Iodine crystals at any pharmacy with a doctor's prescription.

When iodine is heated does any iodine melt?
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.
Why is liquid iodine not visible if crystals are heated in the open air?
When iodine crystals are heated in open air, they sublimate directly from solid to gas without passing through a liquid phase, which means they skip the liquid state. This process is called sublimation. So, liquid iodine is not visible because it transforms directly from solid crystals to a gaseous form.
Is Iodine a metal or nonmetal?
Iodine is a nonmetal but it can be found in solid forms. Iodine experiences sublimation which is the transition from solid to gas, therefore it skips the liquid form.
In Tincture of iodine what is the solvent?

How do you obtain iodine from a mixture of powdered iodine and ammonium chloride?
Iodine is not soluble in water but soluble in organic solvents; ammonium chloride is soluble in water. Method 1: dissolving of the mixture in water, filtering, washing of the filter, recovery of iodine from the filter Method 2: dissolving of the mixture in chloroform, filtering, recovery of iodine from the solution by air evaporation at room temperature
What happened when we put powdered sugar in iodine?
When powdered sugar is added to iodine, it forms a purple-black complex known as a starch-iodine complex. This reaction occurs because iodine reacts with the starch content in the powdered sugar, producing this distinct color change.
What happens if you mix powdered sugar and iodine together?
Mixing powdered sugar and iodine will not have any significant reaction, as iodine is not a strong enough oxidizing agent to react with the sugar. The two substances will likely remain as separate particles with the iodine coloring the sugar.
