They are homogeneous. But they are not a mixture, so they are a pure substance
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.
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.
Heterogeneous, generally speaking water could only be considered homogeneous if there weren't any contaminaton and is distilled without any form of pollution. Good way to remember heterogeneous vs. homogeneous. if you can separate it-it's heterogeneous. ex. on a pepperoni pizza you can pick off the cheese, the bread, and the pepperoni. this is a heterogeneous mixture.
Sugar (sucrose) dissolves completely in water, making a homogeneous solution.
A heterogeneous mixture is a mixture of two or more substances that are not uniformly distributed. The iodine and water in the question are not homogeneous because they are not uniformly distributed.

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.
