... This is because the water molecules pass from a high concentration, i.e. In the water itself, to a low concentration, i.e. In the potato chip. Therefore, the chips in higher water concentrations will have a larger mass than in higher sugar concentrations. The graph above shows a simple curve ... distilled water which I then poured into the test tubes in a percentage ratio giving me the various molar concentrations. 6. I then weighed every potato chip on an electronic balance and recorded the weights. 7. I swiftly put 3 potato chips into each beaker and then started my stopwatch. 3 chips...

... measurements may slightly vary between scales. I predict that the higher the concentration of salt solution the more water will move out of the potato chip. We know that osmosis the flow of one solvent, (water) of a solution through a membrane while the other constituents are blocked and unable ... is a diagram to show the equipment I am going to use: Test-tube rack test tube filled with solution Stopwatch Tile and Scalpel Paper towel Prongs holding chip Preliminary Results Concentration of solution Mass Before Mass After % Change in Mass Distilled Water: 1st attempt 1.66 1.74 4.81927710...

... concentrations. In my planning I said that I would weigh the potatoes but unfortunately they were not available for this investigation. I then swiftly put 1 potato chip into each beaker and then waited for osmosis to occur. I then left it for a day. The next day I drained out the solutions in the ... The next point, 5 M looses approximately 4.0 %. This shows that the water potential of the sugar solution in the beaker is weaker than that of the potato chip. The next, 10 M, looses approximately 8.0 % in mass. This shows that the salt solution has an even weaker water potential than 5 M a...

... record the results, I will do this for all the potato chips. Now I can find out whether there has been a decrease or increase in the weight of the potato chip from the original weight. We either had the choose of using 0g,1g,2g,3g,4g,5g of sugar or using 0g, ½g, 1g, 1 ½g,2g,2 ½g. we decided ... the first one as it basic, so we done the other set but I then repeated the experiment using the other option. I had to make a measurement of each potato chip before and after osmosis had taken place. I tried to make sure my experiment was as precise as I could make it e.g. I made sure I wrote ...

... the graph will go right down, due to the fact that the solution will be isotonic to the potato. In other words, the solution and potato chip are about equal in concentration. The reason for the minus results for 1 molar concentration is that the solution has a lower concentration of water to that ... variable. This means that it will be measured throughout the experiment. I will measure the mass in grams and the length in cm. The potato chip will be measured before it is put in the solution, and after. This will allow us to see whether osmosis has taken place, and to ... quicker the os...
