A student adds iodine solution to egg white and waits for a color change. How long will the student wait?
When iodine is added to a starch solution, the iodine molecules will interact with the starch molecules through a process called iodine-starch complex formation. This complex leads to a characteristic color change from the initial colorless solution to a dark blue-black color, indicating the presence of starch in the solution.
The iodine test is used to test for the presence of starch. Iodine solution interacts with the starch molecules, causing a color change from brownish-yellow to blue or black.
The liquid used to test for starch is called iodine solution. Iodine solution turns a blue-black color in the presence of starch.
The indicator for starch is iodine solution. Iodine changes color from brown to blue-black or purple-black in the presence of starch.
When an indicator such as iodine is added to a solution containing starch, a blue-black color change occurs. This reaction is commonly used to detect the presence of starch, as the blue-black color is characteristic of this complex formed between the starch and iodine molecules.
Forever! Its a protein and iodine solution test for starch.

Petrol changes color when mixed with iodine solution due to covalent bonding.
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.

When a pumpkin is placed in an iodine solution, the starch present in the pumpkin will react with the iodine to form a dark blue or black color. This color change occurs due to the formation of a starch-iodine complex, which is a characteristic reaction used to detect the presence of starch in a substance. The intensity of the color change can vary depending on the concentration of starch in the pumpkin and the concentration of the iodine solution.
If iodine solution is added to a leaf, it will turn blue-black in color. This is due to the presence of starch in the leaf which reacts with iodine to produce this color change.
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.
A dark blue/black color develops when iodine solution is added to starch solution. This color change occurs due to the formation of a starch-iodine complex, where the iodine molecules interact with the helical structure of the starch molecules, resulting in the blue/black color.

Iodine tests for complex sugars. Glycogen is a complex sugar and will change dark purple when iodine solution is added (color is irrelevant, all you really need to know is that the change to a specific color signifies a presence of a macro molecule)
The color not change.
