OSMOSIS Osmosis is the movement of water from dilute solution to more concentrated solution through a semi-permeable membrane. Aims: To investigate osmosis in potato chips placed in different concentrations of sugar solution. Apparatus: 1. 6 test tube 2. Pure water 3. 1Molar sugar solution 4. Clean potatoes 5. 1 borer 6. 1 measuring cylinder 7. 1 scale 8. 1 ruler 9. 1 knife Plan: Firstly, I need to make six solutions with different sugar concentration. I will mix the 1M sugar solution with water. The amount of water present in the solution will determine the overall concentration of the solution. For example, in order to get 10mm³ 0.6M solution, I will use the measuring cylinder to get 6mm³ sugar solution and 4mm³ pure water. The solution now contains 40% water and 60% sugar solution, which is 0.6M. On the other hand, the 1.0M solutions will have no extra water added in and the 0.0M solutions will be pure water. I will then make 18...
