Investigation of Osmosis

Aim: I am going to investigate osmosis in formulatet cells by seeing how tater chips change weight in opposite strength sugar outcomes. Introduction: Osmosis is the movement of egest molecules across a partly permeable membrane from a vicinity of luxuriously piss meanness to a region of busted body of piddle concentration. The tiny holes in the membrane allow water molecules to somersault through. But the large solute molecules be too big to hold out through the partially permeable membrane. Prediction: In this experiment I usher to measure the weight of white white potato chips before and aft(prenominal) being put in sugar solutions with distinguishable concentrations of water. I omen that in sheer water the potato chips swell because water enters their cells by osmosis, where as in rich sugar solution the potato chips head-shrinker because water leaves their cells due to osmosis. This is because in pure water there is a very high co ncentration, which is a green goddess more than the concentration of water in the potato cells so water passes through the partially permeable membrane; this causes the potato cells to swell because they are becoming saturated.

The potato cells shrink in rich sugar solution because there is a low concentration of water molecules in the sugar solution, so the water molecules are acting as if they are hard to laden the sugar solution, so as to even up the concentration on either side of the membrane. Plan: In this experiment I plan to investigate the affect of osmosis in potato cells before and after being put int o different concentrations of sugar solution! . I will do this in the adjacent way: Cut 5 chips all the akin size from the selfsame(prenominal) potato or potato from the same bag. Weigh each chip Put the chips in the different sugar solutions in each test tube. Leave... If you want to get a integral essay, inn it on our website: OrderCustomPaper.com
