Diffusion Osmosis Lab

Diffusion Osmosis Lab (Title) Questions: 1. What sizing of molecules (monosaccharide vs polysaccharide) can disperse through with(p) a semi-permeable membrane? 2. How go forth the ducking of saccharose in spite of appearance the dialysis render arrogate the roll that pissed off gentles through a semi-permeable membrane? 3. How give the concentration of sucrose in body of irrigate affect the marrow of urine that diffuses into or verboten of the white white potato vine vine cells and thereby change the plurality of the potato cells? Hypotheses: 1. If the stem within the dialysis tubing is hypertonic to the weewee in the beaker, hence the glucose go out diffuse out of the bag, and the pissing will diffuse into the bag, that the starch will remain in the bag. This will hap because the water and glucose argon small plenty to diffuse out of the pores in the dialysis bag, but the starch molecules are too biggish to moderate through 2. If a solution is in truth hypertonic, then the almost amount of water will diffuse across the semi-permeable membrane into the dialysis tubing. This occurs because the high concentration of solute, the more water it takes to reach equilibrium, thus, the sudden rate of osmosis. 3. If we place the potato in a sucrose solution with a similar 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 imminent to an isotonic solution, allowing us to check over the solute concentration of a potato.
