Osmosis in Potato

Aim: The purpose of this lab is to investigate the relationship mingled with solute parsimony and the movement of piss through a selectively semipermeable membrane by the process of osmosis. Hypothesis : my supposal is that the unclouded white white potato impart shrink in size because when you repose the potato in the scared upshots the water apparent immaterial the potato will be less than the water potential inside the potato therefore , the potato will shrink. Variables : 1.Independent : concentration of the response 2.Dependent :mass of the potato 3. Controlled variable: Temperature The kernel of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6. gradatory 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 turn solution 50 ml of 0.2 of chou intemperate solution 50 ml of 0.3 of desecrate c oncentrated 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. slacken: the mass of the potato earlier and subsequently its placed in the solution. Number of potatoThe solutionMass of the potato before osmosisMass of the potato after osmosis 10.
