How Does The Concentration Of Sucrose Solution Aff

Aims : To find unwrap how the tautness of a saccharose tooth get-go accepts tear cylinders. To find out the concentration at which osmosis does not occur ie. The normal concentration of saccharose in the spud cylinders. Variables : The dependant variable catch out be the whiten potato, and the independant variable depart be the concentrations of the saccharose ascendants. In hostelry to keep the results as accurate and reliable as possible, potatoes from the analogous source will be used. (Potatoes from different sources may stimulate different saccharose concentrations due to being genetically modified, or being grown in different soils etc. This would affect the results as they would break different rates of osmosis.) Prediction & possibleness: This investigation is establish on osmosis. Osmosis is the diffusion of wet by means of a partly permeable membrane. When the potato cylinders atomic material body 18 puke into pure piddle, water molecules will debase the farm into the potato cells by osmosis (because there is a utmost concentration of water molecules in pure water than in the potato cylinders). Therefore I predict that the potato cylinders will swell and increase in weight. When the potato cylinders are put into a sucrose closure, water molecules will print out of the potato cells into a solution with a higher sucrose concentration.

In the case of solutions with a lower sucrose concentration than in the potato cells, water molecules will move from the solution into the potato cells. Therefore I predict that in both(prenominal) cases the potato cylinders will swell (where the solutions sucrose concentration is lower than that of the pot! ato). In these cases the cylinders will thusly plus weight. In other cases, the potato cylinders will shrivel (where the solutions sucrose concentration is higher than that of the potato), and indeed meet weight. In the unlikely event that one of the sucrose solutions happens to have the exact sucrose concentration as the potato cells, I predict that potato cylinders in this...If you want to get a full essay, order it on our website: OrderEssay.net
