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.

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.
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.
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.
Alcohol
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
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.
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.
it does not turn blue when mixed with iodine. I don't think there is a colour change.
1 tbsp of liquid pectin = 2 teaspoons of powdered pectin
Iodine is a solid, not a liquid. Don't cofuse the solution with the element.
filtration
Powdered milk is made from liquid milk but usually all the fat is removed.
Yes, liquid iodine does have an expiration date. It is important to check the label for the expiration date and to discard any expired liquid iodine to ensure its effectiveness and safety.
No, pure liquid iodine will be I2. Just one type of atom, iodine.
heat it
Iodine has stronger intermolecular forces.
