Part A
Results
We hypothesized that the iodine will diffuse into the bag, turning the inside a darkish blue/black color. We also hypothesized that glucose will diffuse out of the bag, forming a green color (after the Benedict’s test). This experiment was set up using a dialysis tubing bag, balloon clips, beaker, iodine, solution of 1% soluble starch and 15% glucose. The dialysis tubing bag was filled up with starch and glucose, leaving a pocket of air for diffusion of materials, and sealed using balloon clips. At the beginning of the experiment, the inside of the test tube was white and the beaker had a yellow tint. This tube was then placed into a beaker containing water and iodine, and left to sit for a 20 minute time period. After the elapsed time was over, the inside of the tube started to turn dark blue. Once we had recorded the information from this experiment we put the beaker containing the dialysis tube through the Benedict's test, which includes heating up the beaker. The solution within the beaker then turned green. Both of these results were affected from the movement of different materials through the semipermeable …show more content…
This experiment was setup by filling up 4 dialysis tubes with a series of sucrose solutions, each containing the same amount of volume. These solutions each contain a different concentration, which will, in turn, affect each dialysis tube differently. leaving a small pocket of air for diffusion of materials, and sealing the tube using balloon clips. The tubes are then weighed for their initial mass and recorded. Each of these tubes are then placed in a beaker and fully immersed in water. These tubes are left in the beaker for a total of 20 minutes. After the 20 minutes, each tube is then weighed a second time and the mass is recorded. The tubes are all changed in different ways based on the solution that was contained within their
