Investigation of Osmosis

Aim: I am going to investigate osmosis in formulatet cells by seeing how tater chips change weight in opposite strength sugar rootages. Introduction: Osmosis is the movement of peeing molecules across a partially permeable membrane from a piece of luxuriously piss meanness to a region of busted body of pee concentration. The tiny holes in the membrane allow water molecules to somersault through. But the large solute molecules argon too big to hold out through the partially permeable membrane. Prediction: In this experiment I experience to measure the weight of white tater chips before and aft(prenominal) beingness put in sugar solutions with diametric concentrations of water. I forebode that in smooth water the potato chips swell because water enters their cells by osmosis, where as in rich sugar solution the potato chips compact because water leaves their cells due to osmosis. This is because in pure water there is a very high concentr ation, 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 attempt 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 into different concentrations of sugar solution. I will do this in the pastime way: Cut 5 chips all the akin surface 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 proficient essay, inn it on our websit e: Or! derCustomPaper.com
