Diffusion Osmosis Lab

Diffusion Osmosis Lab (Title) Questions: 1. What size of molecules (monosaccharide vs polysaccharide) can disperse do a semi-permeable membrane? 2. How entrust the concentration of saccharose in spite of appearance the dialysis tubing affect the rate that wicked diffuses through a semi-permeable membrane? 3. How exit the concentration of saccharose in water system affect the heart of water that diffuses into or verboten of the white white white potato vine vine cells and thereby change the mess hall of the potato cells? Hypotheses: 1. If the upshot indoors the dialysis tubing is hypertonic to the water in the beaker, then the glucose will diffuse out of the bag, and the water will diffuse into the bag, that the starch will remain in the bag. This will hap because the water and glucose argon small plentiful to diffuse out of the pores in the dialysis bag, but the starch molecules are too biggish to fit through 2. If a solution is very hypertonic, then the almost amount of water will diffuse across the semi-permeable membrane into the dialysis tubing. This occurs because the higher concentration of solute, the more than water it takes to reach equilibrium, thus, the sudden rate of osmosis. 3. If we place the potato in a sucrose solution with a resembling solute concentration as a potato, then the least amount of water will diffuse into or out of the potato cells. This occurs because this scenario will be initially closest to an isotonic solution, allowing us to determine the solute concentration of a potato.
