Is iodine in water homogeneous or heterogeneous?

It's homogeneous. Both ‘homogeneous’ and ‘heterogeneous’ refer to appareance at naked eye. Iodine dissolves poorly in water (1g per 3450ml at 20 celsius), but it dissolves. Since solutions are homogeneous, the optical appareance of iodine in water is homogeneous. read more

Iodine is not very soluble in water. It is a solid at room temperature and water is a liquid. Heterogeneous means present in the same state or solution but iodine isn't in solution. read more

If you mean a solution of iodine, you need to say whether you mean iodide ions in solution, or iodine molecules in solution, although they do not dissolve well, or a solution of iodine in KI, which contains tri-iodide ions. read more

Iodine dissolves in water —. Homogenous. Something that does not dissolve in water would make a heterogeneous mixture. You can tell the difference by the clarity of the stuff. If you can see through it, like apple juice, it's homogenous. read more
