Explanation: 

Detailed explanation-1: -You can use an iodine solution to detect the presence of complex carbohydrates. The yellow-orange iodine will turn blue-black as it reacts with starch. (The iodine solution will show no reaction with simple carbohydrates or sugars.) *Note: Iodine may stain when it comes into contact with the skin.

Detailed explanation-2: -Iodine produces a charge-transfer complex with starch, producing an intense color.
