If we put a drop of iodine on a cut potato, we can see that that the colour changes to blue-black.
This indicates the presence of starch.
This practice is known as starch test:
Starch Test: Add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour. A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow.
