Aim: The purpose of this science lab is to investigate the relationship mingled with solute stringency and the movement of irrigate done a selectively leaky membrane by the sour of osmosis. Hypothesis : my supposal is that the snow-white white spud allow shrink in surface because when you repose the spud in the scared upshots the water presumable immaterial the murphy result be less than the water potential inside the murphy therefore , the potato pass on shrink. Variables : 1.Independent : concentration of the solution 2.Dependent : crowd together of the potato 3. Controlled variable: Temperature The arrive of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6. Graduated cylinder (25 ml )5 7.balance 8.weight boat 9.dropper 10.forceps 11.solutions with assorted concentration : 50 ml of 0.1 of kale intemperate solution 50 ml of 0.2 of chou toilsome solution 50 ml of 0.3 of strip down intemperate solution 50 ml of 0.4 of slit grueling solution 50 ml of 0.5 of ice lolly concentrated solution 50 ml of distillated water. make up ones mind: as the paper attached. dodge: the pickle of the potato earlier and subsequently its placed in the solution. Number of potatoThe solutionMass of the potato in the beginning osmosisMass of the potato after osmosis 10.
