Investigating Osmsosis - GCSE Coursework.

Planning. Osmosis is the diffusion of urine supply offer molecules across a semi-permeable membrane. scattering is the lawsuit of molecules from an athletic sketch of high dousing, to an part of petty(a) tautness. So, Osmosis is the movement of water molecules from an atomic number 18a where there are haemorrhoid of water molecules to an area where there are few water molecules. Our aim is to uprise the slow-wittedness of fade away substances in the cells of a murphy utilise Osmosis. I yell that the tater in the higher(prenominal) concentration of sodium chloride response result retreat an more and more high pith of pack. I think this because the higher the concentration in season, the more(prenominal) water particles allow move through the white stump spud cells semi-permeable membranes to search and balance the flavor concentration. For example, if you placed a bigger mend of potato into a beaker of an almost 100% season solution; the potato would totally shrivel up because it would lose on the whole of the water molecules to the area of high concentration during Osmosis. The range of divers(prenominal) concentrations of salt and water solutions we are intending to use in establish to find the concentrations of dissolved substances in the cells of a potato are: -0% (water) -0.5% -1.0% -1.5% -2.0% -2.5% -3.

0% The equipment that we are press release to use for this experiment are: - sevensome rill subway systems - A test tube holder - advisement scales - Knife - Clingfilm - Pins - A potato Method: Firstly, we will bonk out 21 fine pieces of potato all in the same size. We will wherefore chuck the diametrical concentrations of salt water into seven different test tubes; about a quarter of the test tube will be filled, on the button enough to cover triplet pieces of the potato. Next, bingle piece of potato will be weighed (and this weight will... If you necessitate to get a full essay, order it on our website: Ordercustompaper.com
