Osmosis in Potato

Aim: The purpose of this lab is to investigate the relationship mingled with solute dumbness and the movement of water supply through a selectively leaky membrane by the process of osmosis. Hypothesis : my supposal is that the ashen white spud allow for shrink in size 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 solution 2.Dependent :mass of the potato 3. Controlled variable: Temperature The fare of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6. receive 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 grueling solution 50 ml of 0.3 of dinero concentrated 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. shelve: the mass of the potato earlier and subsequently its placed in the solution.
