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.
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.
When iodine is added to cooked rice, a color change will occur if starch is present in the rice. The iodine will turn from yellow-brown to blue-black if starch is detected, indicating the presence of carbohydrates in the rice. This is because iodine interacts with the starch molecules in the rice, causing the color change.
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
When iodine is mixed with water, it initially forms a solution with a characteristic brown color. Over time, the iodine will partially dissolve in the water, resulting in a mixture of iodine molecules and water molecules. This forms an iodine solution, which can then be used for various applications such as testing for starch presence.
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.

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.
ok, the rice will turn black when you put with iodine. It just like burning, but it is faster then fire!
bread gives black-blue or deep blue color with iodine because starch is present in bread. ...
If you put a drop of iodine on a piece of paper, it will react with starch on the paper turning it blue-black. This is a common test for the presence of starch.
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.
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
Putting iodine in a gas tank can lead to engine damage and potentially cause the vehicle to stop functioning. Iodine is corrosive and can react with the metal components in the engine, leading to serious damage. It is not recommended to put iodine in a gas tank under any circumstances.
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
Iodine is a poison. It can also cause skin damage. It also will cause the noodles to change to a blue black color
