The hypothesis that if sucrose concentration is placed in one of the model cells then the rate of osmosis will increase was supported by the data in this study. To start with, the tap water without any sucrose concentration (M) started at 4.87g and ended with almost the exact same mass after 60 minutes had passed. On the other hand, when 1.20 M of Sucrose Concentration was emerged in water for 60 minutes and pulled out, its mass went from 6.48g to 9.03g.. Osmosis is the net flow of water through a semipermeable membrane. It is basically a unique form of diffusion where the water is the only molecule able to diffuse through the membrane (Wood-Robinson, 2001). The mass of the 1.20M sucrose concentrated dialysis tube became turgid because the

For starters, the scale could be faulty and not giving the correct measurements causing our experiment to be off by some margin. Also, the scale could have not calibrated or checked zeroed meaning. Moreover, the pipettes that were used could have been contaminated with chemicals from previous labs. The sucrose mixture that we had used might of been faulty which would in turn, give us an inaccurate reading on the scale. The tap water could have had substances in it that would have affected our experiment. If we were to carry out this experiment again, we would brainstorm before the lab to point out any possible factors discrepancies that would hinder our results and try as best as possible to avoid those systematic errors. We would also tie the knots of the dialysis tubing closer to the edge because the 0.60M and 1.20M sucrose concentrated tubes looked like they were about to burst.
The independent variable in the experiment would be the concentration of sucrose that goes into the model cells and the dependent variable would be the rate of osmosis through the semipermeable membrane. A controlled variable would be the amount of water that goes into the beakers. The beakers don’t have the exact same amount of water and that could have affected the rate of
