Experiment 2: Concentration Gradients and Membrane PermeabilityIn this experiment, you will dialyze a solution of glucose and starch to observe:The directional movement of glucose and starch.The effect of a selectively permeable membrane on the diffusion of these molecules.An indicator is a substance that changes color when in the presence of a specific substance. In this experiment, IKI will be used as an indicator to test for the presence of starch.
