If iodine is added to a peeled potato, then it will turn-

Correct option is D

The correct answer is (d) Blue.
· When iodine is added to a peeled potato, it turns blue or blue-black in color.
· This reaction occurs because potatoes contain starch, which reacts with iodine.
· Iodine molecules fit into the helical structure of amylose (a component of starch), causing a color change to blue or blue-black.
· This reaction is a common test for the presence of starch in foods and other materials.
Information Booster:
· Iodine test is commonly used in labs to detect the presence of starch in food items.
· Starch is a carbohydrate found in potatoes, grains, and other plant-based foods.
· The blue-black color indicates the presence of amylose, a type of starch that forms a complex with iodine.
· This reaction is a classic example of a chemical indicator reaction, where color change signifies a specific compound.
