Osmosis paper - Essay Exampleother hand, if the concentration of sucrose in a solution is high, then the rate of distribution of water molecules through a selectively permeable membrane would also be high. These concepts were tested in an experiment conducted, which is illustrated below..25M, .5M, .75M, and a control set-up with deionized water. These were placed in individual dialysis tubing which were semi-permeable pocket books, and labeled accordingly. With a string the individual dialysis tubing considered as baggies with corresponding content were tied to seal off, and keep it from spilling out. Next, the individually hustling bags were carefully wiped off excess external surface water with a paper towel. Using an electronic balance, the initial weight of individual bags with contents were interpreted and recorded. Subsequently, four beakers were prepared with 150ml of deionized water. Then, the individual bags were immersed in the prepared beakers with 150ml of deionized wa ter, respectively for thirty five (35) minutes. After the lapse of thirty five (35) minutes, single by one the bags were taken out carefully, wiped from external water and weighed. The results were also noted. After the experimental data were gathered, the materials were cleansed, and returned to the stock room, while the bags were properly disposed. As well, the working laboratory get across was wiped dry and clean.The initial weight of the bag with .25M solution was 17.31g. After the experiment, its weight was 18.23g. The bag with.5M solutions beginning weight was 9.07g, after the experiment, the weight was 10.75g. The bag with .75M solutions beginning weight was 3.7g, after the experiment, the weight was 5.09g. Finally, the initial weight of the control bag was 9.95g, after the experiment, the weight was 10.9g. These findings are reflected on the delay belowTable 1 shows that There were 5.18 % difference in .25M sucrose solution, 16.95% difference in .5M sucrose solution, 31.6 3% difference in .75M sucrose
