Introduction & axerophthol; Aims At present I am investigating Osmosis, and I fork over devised a audition to investigate the rate of it. I put on been provided with tateres, and all(a) the jet laboratory equipment. I exit nerve at 2 variables, angiotensin converting enzyme dis sustained, whizz continuous. For my discontinuous accredited I pass on chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous original I have chosen TIME. Every 5 minutes, I will record the mass of the potato chip, along with the length. I take to to be able to carry out this investigation, and realize near accurate results, to conclude my investigation. My Hypothesis I imply that the rate of osmosis in separately of the types of potatoes will be close to the same. As some potatoes have a different texture, the results will not be scarcely the same. I think the colour of the potato chip whitethorn have an influence on t he rate of osmosis. From past experiments I think the for each genius chip will lose on average virtually 0.25g in mass, and 4mm in length. The longer the potato is in the solution, the much the mass will rise until all the solution is engrossed into the potato.
Method ·         I took 3 potatoes and labelled them A, B & C ·         From each I cut a piston chamber chip using a tool ·         Using a dominion I made sure the length of the chips were the same ·         I weighed each of the chips to the highest level of accuracy - (2 d.p.) ·         I accordingly measured the ch! ips in mm ·         I took 3 runnel tubes, for the chips A, B & C ·         and modify each with 10cm3 of 1 molar sucrose ·         I then inserted the correct...
