I am not quite sure what happens when corn starch and iodine are mixed but when corn starch, iodine and water are mixed, it creates a purple solution. The darkness of the colour mostly depends on the iodine. Without the starch with iodine and water, it is deep yellow or brown.
You can determine if iodine entered the dialysis bag containing starch by performing a simple iodine test. Add a few drops of iodine solution to the bag. If the iodine turns blue or purple, it means that iodine has entered the bag and reacted with the starch inside.
Corn starch, iodine and water.
Iodine is permeable to a plastic bag because the starch's molecules are too large to pass through the bag (starch is a complex sugar made of a large chain of monosaccharides), while the Iodine can pass through since iodine is usually only two Iodine atoms (I2).
This is evidence of the presence of starch in the potato or corn. Iodine reacts with starch, forming a dark blue to black color, which can be a qualitative test for the presence of starch in food or other materials.
Flour and corn starch are measured the same, but the results aren't always the same.
If iodine is placed in a dialysis bag, it will diffuse out of the bag into the surrounding solution, assuming the solution does not contain iodine. This is because the dialysis bag is typically permeable to small molecules like iodine, allowing it to move from an area of higher concentration (inside the bag) to lower concentration (outside). If the surrounding solution contains starch, a color change to blue-black will occur, indicating the presence of iodine, as iodine forms a complex with starch. If there is no starch, the iodine will simply diffuse into the solution without any observable reaction.
corn starch
Yes, corn flour will test positive for starch. Corn is primarily composed of carbohydrates, and a significant portion of those carbohydrates is in the form of starch. When subjected to a starch test, such as the iodine test, corn flour will typically produce a blue-black color, indicating the presence of starch.
Iodine solution is commonly used to test for the presence of starch. When iodine solution is added to a substance containing starch, the mixture turns blue-black in color, indicating the presence of starch.

No, iodine is not a starch. Starch is a carbohydrate found in plants, while iodine is a chemical element that is essential for thyroid function.
