Diаlysis tubing is а selectively permeаble membrane made with the macrоmоlecule, cellulоse. Starch, glucose, water and the IKI reagent arecontained within the dialysis membrane in solution B shown below. Solution A in the beaker, at the start of the experiment in panel (a) contains just water. Diffusion of these molecules occurs, over time, from panels (a)-(c). The only selective criterion for diffusion across a dialysis membrane is the size of the molecule. Between water, (H2O), iodine (I2K; aka IKI), glucose (C6H12O6), and starch (50+(C6H12O6), which molecule is considered large and therefore likely not to pass through a dialysis membrane (Look at the image above, as time progresses, for help)?
