The boiling tubes will be placed in a rack with an equal amount of molar solution. This is because identical solutions are needed for it to be a fair test. The potatoes will be covered with the solutions, if not the water will not be able to pass in and out and the potatoes would dry out. The solutions will all need to be the same temperature and the chips will need to remain in the test tube for the same length of time. The length of time I have chosen to keep the potatoes in the solution is 5 minutes. This should be enough time for the osmosis to take affect. When the potatoes are removed from the solution, the osmosis stops. I will then dry the potatoes using a paper towel being careful so that none of the potatoes fall apart. I will place them into sets of three depending on when which solution they were placed in and weigh and measure them. To get the most accurate results, I will take the average reading of the three pieces. I will then analyse my results and see if they match my prediction.…
