plz help! this is for my science fair project and i rlly rlly need to knw because the project says that when vitamin C is added into the iodine solution mixed with distilled water and cornstarch, it is supposed to turn lighter in color (which was indigo/blue) can someone plz tell me why is that?
What do iodine solution and vitamin C have anything to do with each to do with each other? its for my project?
you can determine the amount of vitamin c in a solution by titrating it with and iodide solution. once iodide has reacted with all of the available vitamin c it will react with the cornstarch and produce a color change letting you know that all of the vitamin c has reacted. check the reference link for more information. good luck.
