Question

did starch diffuse through the membrane? yes no unknown wait fifteen minutes. note the color of the solution in the beaker and the dialysis tube; record the results in the data table.

Explanation:

Starch molecules are large. Dialysis membranes are semi - permeable and usually do not allow large molecules like starch to pass through. Without further information about a positive test for starch in the beaker (such as a color change with iodine), we assume no diffusion occurred.

Answer:

no
