Osmosis Investigation

Introduction & vitamin A; 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 normal laboratory equipment. I entrust nerve at 2 variables, angiotensin converting enzyme dis sustained, whiz continuous. For my discontinuous accredited I clear chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous regular(a) 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 work near accurate results, to conclude my investigation. My Hypothesis I call in that the rate of osmosis in separately of the types of potatoes will be near the kindred. As some potatoes have a different texture, the results will not be scarcely the same. I think the rubric of the potato chip whitethorn have an influence on the rate of osmosis. From past experiments I think the for each hotshot chip will lose on average around 0.25g in mass, and 4mm in length. The longer the potato is in the solution, the to a greater extent the mass will rise until all the solution is abstracted 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 hence measured the chips in mm ·         I took 3 sort tubes, for the chips A, B & C ·         and modify each with 10cm3 of 1 molar sucrose ·         I then inserted the correct...
