Iodine tests for complex sugars. Glycogen is a complex sugar and will change dark purple when iodine solution is added (color is irrelevant, all you really need to know is that the change to a specific color signifies a presence of a macro molecule)


Why is it physical change when purple iodine appears when solid iodine is warmed?

Because the Iodine is undergoing a phase change, which is a physical change. The Iodine is going from a solid to a liquid (I presume), and it's changing color. Those are both examples of physical changes. Phase changes are easily reversible without the use of energy, you could just freeze the iodine, and have the solid again. As for the color change, that's true for a lot of elements, like Mercury. This is not an example of a chemical change because not only is it easily reversible, but because no new substance is formed. You still only have Iodine, but in a different phase, and in a different color.
