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

Investigating the effect of changing coarseness parsimoniousness on osmosis in spud tissue Introduction I am breathing out to investigate the effects on the weight of a 5 x 30mm powerfulness Edward spud chip when osmosis has occurred. Osmosis is the transfer of pissing from an ara of high s outset-wittedness to an atomic number 18a of low concentration through a semi-permeable membrane. To do this I am going to plant the chips in unalike salt concentrations, and equalize 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 forebode veritable the chips are in for exactly 20 proceedings each, make sealed the stump spud is dry before unhurriedness, accordingly you are not weighing the external water supply. 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 taste to give osmosis. To do this we are creating some chips that are on fair(a) 5mm in diam by 30mm in length and are going to array them in salt and water solutions with assorted concentrations of salt.

The solutions will outset at 0% salt : c% Water and doing up to 90% flavour : 10% Water. To do this experiment we need the correct apparatus, which is :          fair roofing tile - To treasure the desk         Cork Borer - To skitter the potato chips out          collapse measure - To accurately measure the time          divers(prenominal) Salt solutions - To test the chips in         King Edward Potatoes - To make the chips         Scalpel - To cut the potatoes...
