Investigating Osmosis Aim: *- Investigating osmosis by monitoring the effect of water concentrations on the mass of potato tissue. Preliminary work: *- Before I started this experiment I previously conducted a simple procedure to confirm a suitable range of readings. I used salt solutions of concentrations 0%, 10%, 50%, 90% and 100%. From my findings, there were variations between concentrations 0% and 50%, however, beyond these concentrations, there were no variations that occurred. I was pleased with these results as they were consistent with my prediction and agreed with what I had already learnt about osmosis. However I was disappointed with my results which I had obtained, due to the fact that I provided myself with a limited range of concentrations which did not successfully give me an in depth scope on the whole experiment in hand. I have therefore decided to use salt solutions, varying in concentrations between 0% and 5%, (1% concentration = 1g of...
