Coursework - Osmosis

Coursework - Osmosis Planning Aim: To investigate what concentration of sucrose solution is isotonic to potato cell sap. Apparatus:0M sucrose (aq) (distilled water) 2M sucrose (aq) Potato Chip cutter Knife Boiling tubes Measuring cylinder (25cm3) Vernier callipers (to nearest 0.1mm) Balance (to nearest 0.01gram) Safety: I will ensure safety around the lab by: wearing safety goggles, laying paper towels, removing baggage from walking space, push stools under the bench, stand up, walk carefully and …showed first 75 words of 978 total…

…showed last 75 words of 978 total…could average them and get a more reliable graph and table of results to base my conclusion on. The potato has approximately have a 0.325M concentration of sucrose in its cells, if I were to put a potato chip in 0.325M solution of sucrose, its size and mass should not change if my results are correct. If both have the same concentration of sucrose, osmosis won't occur, as nothing is higher or lower in concentration.
