Osmosis is the process whereby water moves across a cell membrane by diffusion.Diffusion takes place when the molecules of a substance tend to move from areas of higher concentration to areas of lower concentration.
Figure 13 This is a picture of the potato cores after 24 hours in.8 concentration of sucrose on the electronic balance.
Figure 16 This is a picture of the potato cores after 24 hours in 1.0 concentration of sucrose on the electronic balance. Conclusion: Analysis of results and graph: Analysis Result The results were quite ambiguous and vague.
Suggestion, measure the di water with the graduated cylinder, and fill the other cups to the same level 3.
Obtain 24 potato cores and cut them to equal sizes (about 2.5 cm). Divide your 24 cores into 6 groups and gently blot them dry with a paper towel 5. For each setup (all 6) you will need to calculate a percent mass change.
Figure 12 This is a picture of the potato cores after 24 hours in.4 concentration of sucrose on the electronic balance.
Figure 14 This is a picture of the potato cores after 24 hours in.6 concentration of sucrose on the electronic balance.Using the electronic balance and plastic weighing tray mass (weigh) each group of potato cores and record the data in a table that is labeled with a detailed title and which provides the error measurement of the electronic scale. The table should record the type of solution in the cup and the mass of the potatoes in the cup. Place the potato core sets in their appropriate cup and place in Mr. Finally dump your potato cores in the trash and wash and dry your equipment (cups, tweezers and return them to their stations. To do this you will use the following formula (final mass- initial mass)/initial mass x 100.Boyer s back prep room in the fume hood that is labeled with your block (3B or 4B) hours later (app) you will need to come and measure the mass of your potato cores. You will need to record this data in your data table as well.Figure 7 This is the organized data with errors for each groups of potato cores.Figure 10 This is a picture of the cup labeled with water and the graduated cylinder.Figure 9 This is a picture of our independent variables, which is the concentration of the sucrose.Figure 11 This is a picture of the potato cores after 24 hours in.2 concentration of sucrose on the electronic balance.Figure 15 This is a picture of the potato cores after 24 hours in water on the electronic balance. It was hard to conclude that the more hypertonic potato cores are to sucrose solution, the more weight potato cores gain.Data Chart: Concentration Percentage Change %.2 25 % % % % % Table 1 This table shows our final results. Our X intercept was quite off compared to other groups.The graph should decrease, but our graph was decreasing and suddenly crosses the x- axis then down again. The equation of our graph is y = x Our x- intercept of the best- fit line is (1.34, 0).Although our graph and our results were off, it still partially backed up our hypothesis.
