No. Iodine is an element.
Povidone-iodine is a stable chemical complex of polyvinylpyrrolidone and iodine, used as an antiseptic. Tincture iodine is a solution of iodine in alcohol, commonly used to disinfect skin before surgeries. Tincture iodine is more potent but can irritate the skin, while povidone-iodine is less irritating and commonly used in clinical settings.

When iodine is dissolved in alcohol, the resulting mixture is known as tincture of iodine.
Iodine is not soluble in water but soluble in organic solvents; sodium 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
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Tincture of iodine is a mixture. It is composed of iodine, potassium iodide, and alcohol. These components are not chemically bonded together, so tincture of iodine is classified as a mixture.
heat the mixture iodine will sublime collect the iodine vapour separately and cool
Yes, a mixture of iodine and water is heterogeneous because the iodine does not dissolve completely in water, resulting in distinct particles of iodine suspended in the water. This makes it easy to visually distinguish between the iodine and water components.
The mixture of iodine and ethanol is a heterogeneous mixture because the iodine does not dissolve completely in the ethanol, resulting in visible differences between the two substances.
Iodine is a chemical element; not a mixture, not a compound.
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
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
Tincture of iodine is a homogeneous solution.
They are homogeneous. But they are not a mixture, so they are a pure substance
Iodine crystals can be removed from a mixture by sublimation, where the crystals are heated to turn directly into vapour without melting. The vapour can then be condensed back into solid iodine crystals. This technique allows for the separation of iodine from other components in the mixture.
Tincture of iodine: a mixture of elemental iodine and sodium iodide solved in ethanol and water.
Iodine is soluble in carbon tetrachloride.
