# Essay Question Osmosis

Table 1.4: Individual Data of Change in Mass of Potato Cores in Six Different Sucrose Solution Group 2, 4, 6 and 8 do not have any data for distilled water, 0.2M Sucrose, and 0.4M Sucrose and group 1, 3, 4 and 7 do not have any data for 0.6M Sucrose, 0.8M Sucrose and 1.0M Sucrose because of the lack of time.From table 1.1 in this part of the lab, it is seen that IKI is flowing into the bag and glucose is flowing out of the bag. Knowing of this process is due to the color transformation of the bag, therefore showing that IKI has penetrated the bag.Distilled water was poured into a 250 m L beaker (two-thirds of a cup) with about 4m L of Lugol’s solution (IKI).

The next day, the cores were then removed from the beakers and were blotted gently on a paper towel. The mass difference was calculated and then using the equation: Percent change in mass = Final Mass – Initial Mass/Initial Mass x 100.

Determine the solute, pressure and water potential of the sucrose solution given and answer the questions about the possibility if zucchini cores were used with the sucrose solutions.

The mass difference was calculated and then using the equation: Percent change in mass = Final Mass – Initial Mass/Initial Mass x 100.

The individual and the class average of the percent change in mass were then graphed.

A cork borer (about 5 mm in diameter) was then used to cut four potato cylinders for each beaker, a total of 24 potato cores.

Until the mass of cores were weighed by fours and recorded, the potato cores were kept in a covered beaker.You can view samples of our professional work here.Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of UK Essays.Disclaimer: This work has been submitted by a student.This is not an example of the work produced by our Essay Writing Service.Four cores were then put into each beaker of sucrose solution.Plastic wrap was then given to cover the beakers, preventing evaporation when left to stand overnight.This lab was done to examine and comprehend how diffusion and osmosis works in diverse molarity of sucrose.Also how the solutions permeates through different mediums.15m L of the 15% glucose and 1% starch solution was placed into the bag and the ending of the dialysis bag was tied off, leaving some space for the development of the content within the dialysis bag.The color of the solution was recorded and was tested for the presence of glucose.
