When you pore iodine on a piece of bread, the bread will turn black. Why? Because, the iodine has a chemical reaction with the starch in the bread. This method is great to find out if a food contains starch (I suggest a potato to try next!).
Iodine is used as a indicator for the presence of starch. Since flour is starch it would turn purple or blue-black, which would indicate the presence of starch.
The starch will turn blue-black when iodine is added.
Crisps are made from potatoes which are very high in starch. When iodine is added to starch it forms a complex with it and results in a purplish color. you get the same thing if you put an iodine sol'n on bread or cornstarch.
Only some bread has iodine in it. If the bread was made with iodized salt, then the bread has iodine; otherwise, no.
ok, the rice will turn black when you put with iodine. It just like burning, but it is faster then fire!

Chemical- Iodine reacts with the starch of the bread.

bread gives black-blue or deep blue color with iodine because starch is present in bread. ...

Iodine is a poison. It can also cause skin damage. It also will cause the noodles to change to a blue black color
It depends on what time of bread as some may have more or less. If you wanted to find out then you would need Iodine and the bread you wanted to test and the iodine chart. All starches are carbohydrates. At the moment there's no way to find out the starch without the equipment but as bread is starchy then the carbohydrate contact of it may help you when you compare
im not for sure exactly what happens, but i know fo ra fact that it couldn't be anything good.... lol

Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
