Question

Is crushed potato turns blue black when mixed with iodine solution

Answer 1

Answer:

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.
