Simple Diffusion Activity 1: Simulating Simple diffusion 1.What is the molecular weight of Na+? 22.9 2. What is the molecular weight of Cl-? 35.45 3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ and 200 4. Which materials diffused from the left beaker to the right beaker? Urea‚ NaCl and glucose diffused 5. Which did not? Why? Albumin‚ because the molecular weight exceeded the highest MWCO membrane‚ thus being to large to pass through

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was
