Iodine test is a test used to determine the presence of starch in a particular substance.
A positive result will yield the purple-black color.
For example, adding a few drops of iodine solution to potato will seem purple-black color in this solution --->This means that the potato contains starch.

The principle of the iodine test is based on the formation of a blue-black color complex when iodine reacts with starch. Iodine is able to penetrate the helical structure of starch molecules and form a complex that gives the characteristic color change. This test is commonly used to detect the presence or absence of starch in a sample.
