Investigating Osmsosis - GCSE Coursework.

Planning. Osmosis is the diffusion of peeing supply molecules across a semi-permeable membrane. dissemination is the lawsuit of molecules from an athletic field of higher(prenominal) concentration, to an area of low-down concentration. So, Osmosis is the movement of water molecules from an area where there are often of water molecules to an area where there are few water molecules. Our aim is to uprise the concentration of dissolved substances in the cells of a murphy utilise Osmosis. I predict that the potato in the higher(prenominal) concentration of sodium chloride solvent result move back an increasingly high pith of weight. I think this beca determination the higher the concentration in salt, the more(prenominal) water particles volition move with the potato cells semi-permeable membranes to search and balance the salt concentration. For example, if you placed a larger mend of potato into a beaker of an almost one hundred% salt solution; the potato would completely shrivel up beca custom 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.

We will then chuck the differ! ent concentrations of salt water into seven different examen tubes; about a quarter of the test tube will be filled, just enough to concoct three pieces of the potato. Next, bingle piece of potato will be weighed (and this weight will... If you necessitate to get a full essay, narrate it on our website: OrderCustomPaper.com
