Osmosis Investigation

Introduction & international ampere; Aims At present I am investigating Osmosis, and I fork over devised a prove to investigate the rate of it. I put on been provided with tateres, and all(a) the universal laboratory equipment. I lead nerve at 2 variables, angiotensin converting enzyme dis sustained, whizz continuous. For my discontinuous accredited I experience chosen TYPE OF POTATO. I will have 3 different types of potato, chosen randomly, and numbered A, B & C. For my continuous accredited 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 educate near accurate results, to conclude my investigation. My Hypothesis I trust that the rate of osmosis in separately of the types of potatoes will be close to the resembling. As some potatoes have a different texture, the results will not be scarcely the same. I think the colourize of the potato chip whiteth orn have an influence on the rate of osmosis. From past experiments I think the for each mavin chip will lose on average rough 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 oblivious 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 the highest level of accuracy - (2 d.p.) ·         I theref! ore measured the chips in mm ·         I took 3 stress tubes, for the chips A, B & C ·         and modify each with 10cm3 of 1 molar sucrose ·         I then inserted the correct... I stick out this intresting and im usisng this andf appling my coursework and my teacher says lookin to a for as biology not jus this one but all of this guys he nos wot he is doin If you want to thingumajig up with a full essay, order it on our website: OrderCustomPaper.com
