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.

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.
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
Starch is not the indicator. Iodine is the indicator of starch.
