When iodine is added to bread, it reacts with the starch present in the bread. This reaction causes the iodine to turn a blue-black color, allowing for the detection of starch. This can be used as a test to check if the bread contains starch as an ingredient.
Bread turns blue-black when iodine solution is added due to the presence of starch. The iodine reacts with the starch molecules in the bread, forming a complex that gives this characteristic color change.
When iodine is added to cornstarch, a blue-black complex is formed. This is utilized as a simple test to detect the presence of starch in a given substance.
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
iodine is soluble in CHCl3. Liquid become purple in color.
When iodine is added to water, it forms a solution where the iodine molecules dissociate, producing a characteristic brown color. This color is due to the interaction of iodine molecules with water molecules.

It turns black!
Only some bread has iodine in it. If the bread was made with iodized salt, then the bread has iodine; otherwise, no.
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!).
When iodine is added to cornstarch, a blue-black complex is formed. This is utilized as a simple test to detect the presence of starch in a given substance.
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.
ok, the rice will turn black when you put with iodine. It just like burning, but it is faster then fire!
The colour of the iodine will turn from yellowish brown to dark blue

it will change into blue black colours.
No, I don't think so.
As you know that iodine act as indicator for testing of starch so when a drop of iodine is added to starch it turns bluish black but when added to distilled water nothing happens except the colour of water which turns brown and its is the colour of iodine.
