When a pumpkin is placed in an iodine solution, the starch present in the pumpkin will react with the iodine to form a dark blue or black color. This color change occurs due to the formation of a starch-iodine complex, which is a characteristic reaction used to detect the presence of starch in a substance. The intensity of the color change can vary depending on the concentration of starch in the pumpkin and the concentration of the iodine solution.
