Evaporation.
A mixture of iodine and ethanol is considered heterogeneous because iodine does not dissolve in ethanol and will remain visibly separate as a solid in the liquid ethanol.
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.
The solute would be iodine, and the solvent would be tincture
The reaction of ethanol with NaOH and iodine will yield iodoethane (ethyl iodide) as the product. The alcohol group in ethanol will be replaced by the iodine atom in the presence of NaOH.
When ethanol reacts with iodine, it forms a yellow-brown solution due to the formation of iodoethane and hydrogen iodide. The reaction is a substitution reaction where iodine replaces a hydrogen atom in ethanol.

Tincture of iodine: a mixture of elemental iodine and sodium iodide solved in ethanol and water.
Iodine is dissolved in ethanol at any temperature.
No. Iodine is itself a chemical element; it contains no other element. If you mean instead tincture of iodine that has no iron in it either. It's a solution of iodine and an iodide in ethanol and water.
how can we separate iodine and napthelena
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
