This activity shows which foods contain starch. The indicator used is iodine. Iodine, a yellowish brown liquid, when added to rice and potato turns blue black. This is because when iodine reacts with starch, it forms a complex made up of polyiodide chains. Such a reaction is not seen when iodine is added to sugar and salt.
