Webb10 juli 2024 · Why is starch iodine complex blue? Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. This makes a linear triiodide ion complex with is soluble that slips into the coil of the starch causing an intense blue-black color.
