24. Lugol's Iodine is placed on the cut side of a potato.  What is likely to happen?

Explanation

When Lugol's Iodine is placed on the cut side of a potato, the potato will turn black. This is because Lugol's Iodine reacts with the starch present in the potato, forming a dark-colored complex known as iodine-starch complex. This reaction is commonly used as a test for the presence of starch. Therefore, the black color change indicates the presence of starch in the potato.
