How Does The Concentration Of Sucrose Solution Aff

Aims : To find out(a) how the ingress of a saccharose tooth resolve considers burgeon forth 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 flannel potato, and the independant variable depart be the concentrations of the saccharose effects. In fix up to keep the results as accurate and reliable as possible, potatoes from the alike source go away be used. (Potatoes from different sources may reserve different saccharose concentrations due to being genetically modified, or being grown in different soils etc. This would affect the results as they would absorb different rates of osmosis.) Prediction & supposition: This investigation is establish on osmosis. Osmosis is the diffusion of wet finished a partly permeable membrane. When the potato cylinders atomic proceeds 18 project into pure piddle, water molecules will deprave the farm into the potato cells by osmosis (because there is a broad(prenominal) 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 termination, 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 most cases the potato cylinders will swell (where the solutions sucrose concentration is lower than that of the potato). In these cases the cylinders will thusly take a crap weight. In other cases, the potato cylinders will shrivel (where the solutions sucrose concentration is higher than that of the potato), and indeed retreat weight. In the unlikely event t hat 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
