Why is the mixture of iodine and ethanol a heterogeneous

Answer 1

The mixture of iodine and ethanol is heterogeneous because the iodine particles do not dissolve completely in the ethanol. Instead, the iodine remains as a separate phase within the ethanol, creating a two-phase system with visible differences in properties such as color and texture. This lack of uniformity throughout the mixture is characteristic of a heterogeneous mixture.
