Osmоsis is the diffusiоn оf wаter аcross а selectively permeable membrane. Because osmosis is a type of diffusion, water moves from an area of higher water concentration to an area of lower water concentration. In this laboratory simple diffusion will be demonstrated, and you will observe osmosis in animal cells (e.g. red blood cells and decalcified chicken eggs).First, view the following video: Osmosis Video Khan AcademyNext, you will observe the effect of osmosis on red blood cells (RBCs).RBCs, also known as erythrocytes, are the formed elements of blood that carry oxygen and some carbon dioxide. Overall, RBCs contain approximately 0.9% solutes (e.g. hemoglobin) and 99.1% solvent. In cells, the solvent is water.Take a look at the demonstration slides below. The labeled slides of RBCs were exposed to the following treatments: Slide A: 3-4 drops of distilled water (0% saline, 100% water)Slide B: 3-4 drops of 0.9% salineSlide C: 3-4 drops of 5% salineRemember that during osmosis, water will move from a higher water concentration to a lower water concentration until equilibrium is reached. Therefore, to determine the net (overall) movement of water molecules during osmosis, it is easiest when you look at the water (solvent) concentration of the solutions. Therefore, for slide B in which 0.9% saline is added, the solution contains 99.1% water, since the solute and solvent should add up to be 100%.Below, match the slide with the result that occurred.
