The Diffusion of Glucose and Iki: an Experiment Report

WebA cell membrane is similar to dialysis tubing. In activity A, dialysis tubing was used to model diffusion across the cell. The glucose in the dialysis bag went from clear to blue with a negative test result before and after and the iodine-potassium iodide in the cup went from dark red to copper colored. The results were positive before and after. WebA dialysis bag is filled with distilled water and then placed in a sucrose solution. The bag’s initial mass is 20g, and its final mass is 18g. Calculate the percent change of mass, showing your calculations in the space below. 18g (final mass) – 20g (initial mass) / 20g (initial mass) = 2/20g x 100 = 10% change of mass.
