When starch is mixed with iodine in water, an intensely blue colored starch/iodine complex is formed. Many of the details of the reaction are still unknown. Apparently, the Iodine gets stuck in the coils of beta amylose molecules. Personally, I ha...

Iodine Test. Using iodine to test for the presence of starch is a common experiment. A solution of iodine (I 2) and potassium iodide (KI) in water has a light orange-brown color.If it is added to a sample that contains starch, such as the bread pictured above, the color changes to a deep blue.

Iodine Test: When following the changes in some inorganic oxidation reduction reactions, iodine may be used as an indicator to follow the changes of iodide ion and iodine element. Soluble starch solution is added. Only iodine element in the presence of iodide ion will give the characteristic blue black color.

The ensuing transfer of charge between the iodine and the starch alters the manner in which electrons are confined and, in turn, their energy-level spacing. The new energy-level spacing is sufficient to absorb visible light selectively, producing a bluish tint. There must be iodine and iodide ions present in order for this reaction to take place.

The result of reaction between starch and iodine solution [Wikimedia] Let’s see how the re­ac­tion of starch and io­dine can be use­ful in dai­ly life. It’s sim­ple: if you have two un­la­beled con­tain­ers of soda and starch at home, and you don’t want to work out which one is which by tast­ing them, add a drop of io­dine. ...
