Discuss how the concentration of sucrose solution influences penetration rate Introduction: Diffusion is the movement from high to low concentration until uniform distribution of particles. An example of diffusion is when spraying the aerosol. Particles will diffuse from high concentration of nozzles to other parts of the room. This is a scent movement. Permeation is the passage of water molecules from a weaker solution through a partially permeable membrane through a stronger solution.
Permeation is the diffusion of water molecules from the high concentration sucrose solution zone through the selectively permeable membrane to the low concentration sucrose solution zone. Water molecules move down the concentration gradient during permeation. Two illustrative illustrations of permeation are shown in FIG. 1, which shows the diffusion of water molecules from the high sucrose solution zone through the selectively permeable membrane to the low concentration sucrose solution zone. Figure 2 shows the concentration gradient where water molecules diffuse along the concentration gradient
Water is a variable that is tested for this activity because penetration is the diffusion of water from high to low concentration and because it is responsible for the mass gain of each sucrose solution. The amount of sucrose solution, dialysis bag and time will affect the results of this experiment. The greater the amount of sucrose, the more water will enter the dialysis bag. The dialysis bag is influenced by the size of the pore size with respect to water molecules. There is a possibility that water movement may be affected if there is time. The longer the time, the more time the water will enter the dialysis bag, not the short time.
In my preliminary survey, we used five concentrations of sucrose to determine if concentration affects penetration. I now decided to use 9 different concentrations of sucrose solution ranging from 0% to 100%. I did this to confirm that I have a series of results that I can draw. I also put chips into the solution for 5 minutes; I think the time is not enough for penetration. I believe that perhaps longer time will make more infiltration. In the final experiment, soak the tip in the solution for 10 minutes to increase the osmotic activity.
