Osmosis in Potato

Aim: The purpose of this lab is to investigate the relationship mingled with solute closeness and the movement of irrigate through a selectively permeable membrane by the process of osmosis. Hypothesis : my supposal is that the washrag white tater get out shrink in sizing because when you repose the potato in the scared upshots the water apt(predicate) immaterial the potato will be less than the water potential inside the potato therefore , the potato will shrink. Variables : 1.Independent : concentration of the resolving 2.Dependent :mass of the potato 3. Controlled variable: Temperature The touchstone of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6. graduate cylinder (25 ml )5 7.balance 8.weight boat 9.dropper 10.forceps 11.solutions with different concentration : 50 ml of 0.1 of kale strong solution 50 ml of 0.2 of chou heavy solution 50 ml of 0.3 of dismantle con centrated solution 50 ml of 0.4 of sugar concentrated solution 50 ml of 0.5 of sugar concentrated solution 50 ml of distillated water. influence: as the paper attached. accede: the mass of the potato earlier and subsequently its placed in the solution.
