Egg Osmosis Lab Report
Hypothesis - If the glucose and starch solution stays within the beaker of water for a longer period of time, then more water will travel through the selectively permeable membrane due to the effects of diffusion on the solution.

If the level of sucrose within the solution increases, then the effects of osmosis will cause the change in mass to also increase due to higher concentrations of sucrose and the increased net movement of the water molecules within the solution.

Analysis - When the glucose and starch solution was placed in the beaker of water for 25 minutes, the solution changed color from white to purple black. My hypothesis was validated because the experiment resulted in a change in color due to the effects of diffusion on the

In order to find the molarity of a chicken’s egg, students would first have to peel the shell of the egg in order to expose the semipermeable membrane. Then, students are required to place the egg into distilled water, which would act as the solvent and would cause the water to diffuse through the membrane and reduce the high concentration of sugars within the egg, which are the solutes.

Once the eggs have been submerged in water for 30 minutes, it is then time for the students to weigh the eggs before placing them in the sucrose solution. Weighing the eggs will allow students to calculate the initial mass, which will then be subtracted from the final mass once it has also been determined. Once students have found the initial mass of the eggs, they will then need to place the eggs in the sucrose solution and let it sit for 30 minutes. Doing so will fill the egg with proteins and sugars, which will give students a change in mass when they weigh the eggs and calculate the final mass. By subtracting the initial mass from the final mass, students will have received the molarity of the

    When a substance is released into an area, the random movement of its molecules results in a multitude of collisions. These collisions, in turn, lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration, where there will be more collisions, to areas of low concentration, where the number of collisions will be much less. This process of dispersion will continue until there is no net gain or loss of molecules in an area. The process by which this equilibrium occurs is called diffusion. Diffusion is vitally important to biology on many levels; individual cells, organelles, and even whole organisms rely on diffusion to carry out the processes essential to life. One especially important aspect of diffusion is osmosis, or the diffusion of water. This often occurs across a semi-permeable membrane…

    This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become turgid because the water molecules that are present in the swede will move away from an area of higher potential of water molecules to an area that has a lower potential of water molecules, this means that the swede sample will gain mass and become full almost to an extent where it is ready to burst. The swede samples that are going to be put in a test tube with a high potential of sucrose solution will become flaccid because the swede cylinder will have a higher potential of water molecules and so these molecules will diffuse into the sucrose solution as it has a lower water potential, this means that the potato sample will shrivel and loose mass.…

    The last jar I filled halfway. One of the full jars I filled with 12 tablespoons of sea salt and mixed it. The other full jar I left with only clear tap water. The jar that was half full I mixed in six tablespoons of sea salt. I put an egg in each jar. After I put the egg in the jar that was half full, I filled the rest with clear tap water so that the bottom half was salt water and the top half was clear tap water. I Recorded the results of each jar and took a picture of each. The jar that was only water: the egg went straight to the bottom. The jar that was all salt water: the egg floated on the top. The jar that was half salt water, half tap water: the egg submerged but stayed perfectly between the salt and tap water. If I were to do this project again in the future, I would use multiple mixtures in the water and test which substances were the most dense. Some problems could be that the amount of salt and water can vary and the size and weight of the eggs can also vary. To fix these problems, I could use the same egg for all of the mixtures. I could also do exactly the same amount of water and substances put in the…

    If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose, the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic, which is why water moves from the bag to the beaker and the bag loses mass.…

    - In this experiment three zip-loc bags were filled with a solution of starch. Each bag was placed in different beakers filled with IKI indicator and placed at different temperatures. When Iodine reacts with starch, it turns purple. The rate that a solution diffuses along a grain or membrane Is related to the concentration, the type of membrane and the temperature. Because the concentration of the solutions and type of membrane is the same, the only factor to determine the rate of diffusion in this experiment is the temperature. When molecules are placed in a hot temperature they become excited; And the higher the temperature the higher the rate of diffusion.That is why in this experiment, the zip-loc placed in the hot water bath achieved the fastest rate of diffusion when compared to the solutions placed in the refrigerator and in ambient room air.…

    The first experiment involves the facilitated diffusion of glucose. This simulation depicts the varied rates of diffusion for glucose with differing numbers of glucose carrier proteins. As the number of glucose carrier proteins increases the rate of diffusion also increases. The second experiment simulates filtration of sodium, urea, glucose, and powdered charcoal. These…

    Vinegar Egg Lab

    When the experiment was finalized the vinegar solution enlarged the eggs mass. Before the vinegar solution it was 55.1 grams and after the solution it was 67.9 grams. The volume of the egg was also increased. At the beginning it was 50 mL after the solution it was 60 mL; it had a 10 mL difference. It is visible that a hypotonic solution was present. This rejects the hypothesis made. When the egg was placed in 150 mL of vinegar and left intact overnight the egg did sink to the bottom and remain that way, however, the mass was increased instead of keeping it the same, by approximately 13 grams. Furthermore, the volume was also increased it did not remain the same. By analyzing the data it can be determined that the water had a larger concentration and did not have to balance out with the vinegar. The vinegar acted in a peculiar way although it eroded the shell and took some weight off the water flowed inside the egg due to the low concentration of the vinegar.…

    The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic, isotonic, and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell, it keeps the cell the same it’s just in a different environment.…
