e potato blocks used in this experiment are rich in starch molecules. Iodine potassium iodide (IKI) is a starch indicator that forms a blue-black complex in the presence of starch. What does the width of the black of the potato cube represent in the context of diffusion? How does the width of the black iodide starch complex of each potato block compare to the others? Why?
