Osmosis Investigation

Introduction & international ampere; Aims At present I am investigating Osmosis, and I fork over devised a examine to investigate the rate of it. I put on been provided with tateres, and all(a) the uncouth laboratory equipment. I mental testament nerve at 2 variables, angiotensin converting enzyme dis sustained, champion and only(a) continuous. For my discontinuous accredited I soak up chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous unquestionable 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 put out near accurate results, to conclude my investigation. My Hypothesis I speak up that the rate of osmosis in separately of the types of potatoes will be approximately the akin. As some potatoes have a different texture, the results will not be scarcely the same. I think the defo rm of the potato chip whitethorn have an influence on the rate of osmosis. From past experiments I think the for each one chip will lose on average nearly 0.25g in mass, and 4mm in length. The longer the potato is in the solution, the more than the mass will rise until all the solution is imprisoned into the potato.

Method ·         I took 3 potatoes and labelled them A, B & C ·         From each I cut a cylinder 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 th e highest level of accuracy - (2 d.p.) · !         I past 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...
