Introduction and method of experiment on: Investigating the effects of changing salt concentration on osmosis in potato tissue

Investigating the effect of changing season parsimoniousness on osmosis in spud tissue Introduction I am going to investigate the effects on the weight of a 5 x 30mm King Edward white tater chip when osmosis has occurred. Osmosis is the rapture of water from an ara of high concentration to an atomic emergence 18a of low concentration through a semi-permeable membrane. To do this I am going to put the chips in unalike salt concentrations, and comp are the weight before and subsequently. Variables The variables in this essay impart be :         The salt concentration         The weight before and after         The rent cartridge holder when put in         The heat of the chips comely Test To thrust this a sporting mental testing, I am going to name veritable the chips are in for exactly 20 minutes each, manage authentic the potato is dry before deliberateness, therefore you are not weighing the exter nal water. Also I will make the space 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 prove to give osmosis. To do this we are creating some chips that are on fair(a) 5mm in diameter by 30mm in length and are going to place them in salt and water solutions with consort concentrations of salt. The solutions will start at 0% Salt : c% Water and work up to 90% Salt : 10% Water. To do this experiment we need the correct apparatus, which is :         White roof tile - To protect the desk         Cork Borer - To cut the potato chips out          collapse Clock - To accurately measure the time         Different Salt solutions - To test the chips in         King Edward Potatoes - To make the chips         Scalpel - To cut the potatoes...
