Osmosis in Potato

Aim: The purpose of this lab is to investigate the relationship mingled with solute concentration and the movement of urine through a selectively leaky membrane by the process of osmosis. Hypothesis : my supposal is that the tweed white potato give shrink in coat because when you repose the potato in the scared upshots the water presumable immaterial the potato will be less than the water potential inside the potato therefore , the potato will shrink. Variables : 1.Independent : concentration of the theme 2.Dependent :mass of the potato 3. Controlled variable: Temperature The measurement of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6. calibrated 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 intemperate solution 50 ml of 0.2 of chou concentrate solution 50 ml of 0.3 of prize concentra ted 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. panel: the mass of the potato earlier and subsequently its placed in the solution.
