Diffusion lab question?
rlc157 asked:
Ok so theres this question thats really confuzing me. Can someone explain this to me with the answer?
IKI (iodine potassium iodine), when mixed with starch, reacts to cause a color change from clear to a blue/black. Glucose test strips are impregnated with a chemical that will change color when exposed to glucose. Given this information, which substance(s) do you believe diffused in or out of the dialysis tubing?
Divya, what substance?
