Osmosis Investigation

Introduction & angstrom unit; Aims At present I am investigating Osmosis, and I fork over devised a experiment to investigate the stray of it. I put on been provided with tateres, and all(a) the common laboratory equipment. I provide nerve at 2 vari competents, angiotensin converting enzyme dis sustained, one continuous. For my noncontinuous accredited I dedicate chosen TYPE OF POTATO. I lead have 3 unalike types of potato, chosen randomly, and numbered A, B & angstrom unit; C. For my continuous veritable I have chosen TIME. Every 5 minutes, I pass on record the mass of the potato detach, on with the distance. I take to to be able to carry out this investigation, and make water near accurate results, to answer my investigation. My Hypothesis I hold that the rate of osmosis in separately of the types of potatoes bequeath be virtually the same. As rough potatoes have a diverse texture, the results will not be scarcely the same. I think the colour of the potato chit whitethorn have an entice on the rate of osmosis. From medieval experiments I think the for severally one chip will lose on bonny around 0.25g in mass, and 4mm in length. The longer the potato is in the settlement, the more the mass will rise until all the solution is absorbed into the potato.

Method ·         I took 3 potatoes and labelled them A, B & C ·         From individually I be intimate a cylinder chip using a tool ·         victimization a dominion I made sure the length of the chips were the same ·         I weighed each of the chips to the highest take of accuracy - (2 d.p.) ·         I then measured the chips in mm ·         I took 3 test tubes, for the chips A, B & C ·         and modify each with 10cm3 of 1 molar sucrose ·         I then inserted the correct...
