Osmosis In Potatoes

Investigate what effect different levels of concentration of saccharose solvent have on the movement of water via osmosis in flannel potato vinees. EQUIPMENT saccharose resolvent (0.2M, 0.4M, 0.6M, 0.8M, 1.0M) Distilled water (0.0M) Potatoes Cork rock drill Boiling undergrounds Boiling pipage rack Stop clock Balance (0.0 decimal places) Tweezers Measuring cylinder Ruler rule manage 6 pieces of potato with a cork rock drill and racetrack them to the kindred aloofness of approximately 5 cm (measure with a ruler) Measure out 25cm³ of water and separately of the sucrose issues, victimisation the measuring cylinder. The measurements for the resolves have to be perfect as to not change the outcome of the experiment. Pour into simmering tubes, crowing the mingled concentrations. Label boiling tubes with concentration of sucrose solution murder measurements of each potato tube ( hatful) on the par wholeelism and shew in a suitable table. Always use the same balance to weigh the mass of the each tube as measurements whitethorn differ slightly between scales. The surface field of operations of the potato tubes will be kept the same by having all the tubes the same size. They must be kept the same because the measurement of surface area exposed to the solution may chance on the rate of osmosis. Be sure to timbre which strength solution is put in each. Place potatoes in sucrose solution and leave for 30 minutes, using the stopwatch for accurate timings. shift potato tubes and pat off redundancy sucrose solution with a paper towel, in the ensnare that they came out of the boiling tubes as to not confuse which tube came from which solution. Take measurements of mass and length of each tube and record book appearance in a suitable table. This experiment should and then be reiterate to ensure a fair run as the results give the bounce then be compared. . prediction It could be predicted that a s the concentration of the sucrose increases! , the mass and length of the potato tube will decrease. The think behind this, is that the higher(prenominal) the concentration of sucrose in...If you want to win a exuberant essay, order it on our website: OrderCustomPaper.com
