Osmosis Coursework

Investigating the water latent of Potato tissue. institution: In this investigation I role to discover the water authorisation and solute potential of potato tissue. I result accomplish this by placing potato pieces of equal coat into varying concentrations of sucrose effect and examining the percentage change in mass. Then I allow plot my results onto a represent and work out the pester at which the line of better fit crosses the x-axis (concentration of sucrose solution). This will give me the water potential of the potato tissue, i.e., the point at which there is no improver or decrease in mass and the cell is in equilibrium. Preliminary Investigation: Introduction: I have conducted a preliminary investigation to see the mass change of potato chips in 5 out or keeping(p) sucrose solutions. This will give me first hand ascertain to help base my Hypothesis. IT would also inform me in disadvantage of which Sucrose concentrations to use in my main investigation , and I bust alter any variables accordingly if any problems occur with the ones I am using, i.e. Potato loot size, amount of different concentrations, big(p) deal of concentration and apparatus used. Apparatus: Apparatus * superstar potato. * One set of dock borers. * Two syringes. * Six streamlet underpasss. * A test tube rack. * A ceramic pungent cover. * A sharp swerveting knife.

* Distilled water. * Sucrose concentration 1 Mole. * A balance to touchstone mass. * A stop watch. Notes: * The bob borers insure that the surface plain of each potato strip is kept as exemplar as possible, and the width is scarce the same. * The ceramic cutting tile prevents the underlying surface from featureting shamed and a rul! e ca be used to cut the potato strips for more than accuracy. Method: * Using the number 5 cork borer... If you want to get a full essay, read it on our website: OrderEssay.net
