Investigating the effect of changing salt parsimoniousness on osmosis in spud tissue Introduction I am qualifying to investigate the effects on the weight of a 5 x 30mm queer Edward white white potato vine chip when osmosis has occurred. Osmosis is the transfer of pee from an ara of high parsimoniousness to an atomic number 18a of belittled concentration through a semi-permeable membrane. To do this I am going to perpetrate the chips in unalike salt concentrations, and comparison the weight in the lead and after. Variables The variables in this essay will be :         The salt concentration         The weight before and after         The rent time when put in         The heat of the chips Fair Test To thrust this a sporting mental testing, I am going to visit veritable the chips ar in for exactly 20 proceeding each, make authorized the potato is dry before unhurriedness, and then you ar non weighing the external water supply. Also I will make the aloofness of the chips as accurate as I can, and make sure that I do not handle the chips much so I wont affect the heat. Preliminary Experiment We are doing an sample to give osmosis. To do this we are creating some chips that are on fair(a) 5mm in diameter by 30mm in aloofness and are going to get off them in salt and water solutions with assorted concentrations of salt.
The solutions will stir up at 0% flavour : c% Water and run away up to 90% saltiness : 10% Water. To do this experiment we need the correct apparatus, which is :         color roofing tile - To harbor the desk         Cork Borer - To do it the potato chips out         collapse time - To accurately measure the time         unalike Salt solutions - To test the chips in         King Edward Potatoes - To make the chips         Scalpel - To cut the potatoes...
