Differences Between Osmosis And Corn Syrup

In the rubber egg lab also known as the osmosis lab, I first measured the circumference of the egg which was 6 inches. The egg had no cracks and was hard. I placed the egg in the vinegar and within seconds the egg started to bubble. These bubbles were carbon dioxide. After 72 hours the shell of the egg had started to dissolve or flake. This would be considered passive transport as the vinegar diffused across the egg shell without any force. Seventy-two hours into the experiment the membrane was exposed, and had a circumference of 8 inches. Before the egg had a shell and you couldn’t see through it but once the vinegar acted as an acetic acid it broke down the shell and left a yellow membrane that felt like rubber this is an example of diffusion. I then placed the egg in another container and put corn syrup over the egg for 24 hours. The egg had shriveled and shrunk, the water had left the egg and went into the syrup and that is what caused the egg to shrink. The corn syrup is essentially pure sugar with very little water so the osmotic pressure is very low. I then placed the shriveled egg in water and waited for another 24 hours. After observation the egg had no

We put our egg into syrup because we wanted to see if the color would change to brown and if the size would change. The egg started out as whitish or light orange and changed to brown with bits of white. It changed color because the syrup was trying to diffuse into the egg. However, because the egg had bits of white, the color only stained the membrane. This means that the diffusion did not fully occur. The egg initially weighed 88.3g but after the experiment, it had decreased to 48.39g. I believe this happened because the egg was hypertonic, and so the size decreased. The texture of the egg started out as squishy and slightly chalky and ended as being deflated and having a smooth membrane. The texture most likely changed because the texture of the syrup diffused into it and changed it. The egg deflated most likely because the egg was hypertonic. These changes show that the egg membrane is selectively permeable because it let the egg albumen out of the egg, but the syrup was only able to color the egg and not diffuse into the egg completely. I believe that passive transport happened, but precisely diffusion. If I could do the lab just on these changes, I would keep the egg in the syrup for longer until it stopped deflating and then find out

Osmosis took place in the egg under a variety of conditions because the membrane of the egg has tiny openings where water can pass through from high to low concentrations. On day one, it was a hypotonic solution because the higher concentration of water in the vinegar moved to the smaller concentration in the egg. This means the egg was filled with water, which resulted in the eggs increase in size. On day three, the hypotonic solution occurred because the corn syrup had a lower concentration of water than the egg. That means the egg released water into the corn syrup, which resulted in the eggs decrease in size. On day four, the egg was placed in water which resulted in an isotonic solution where the concentrations become even. This

The primary purpose of the lab was to test and observe the effects of the process of osmosis on decalcified eggs. Before the process, the initial weights of the eggs were taken and noted. Two eggs were then immersed in a deionized water solution. The same was repeated to the other two solutions of 20% and 40% sucrose. The weights of the eggs were measured after 15 minutes to note the change in mass due to osmosis and again after 60 minutes to take the final measurement. Overall, while some human error might arise in the weighing process, care was taken in handling the eggs and during the weighing process. As such, it was found that the eggs behaved as predicted. It was found that the eggs placed in the hypertonic solution lost

A 25 cm3 aliquot of the diluted eggshell solution was pipetted to a clean beaker. The beaker was placed on a magnetic stirrer and a pH meter was put into the solution.

How will the cell change as a result of being placed in different types of liquids? In this experiment we studied and tested the effects corn syrup, vinegar, and distilled water had an egg. When placed in vinegar the egg will double in size because the egg will soak up the vinegar. When placed in corn syrup the egg will shrink in size because the corn syrup will cause the egg to throw everything out.

The purpose to this experiment was to study the effect of osmosis in de-shelled chicken eggs in different percentages of sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed in fifteen minute intervals. Then, each weight was recorded and graphed. The results showed that the egg in the water solution gained the most weigh and the only other egg that gained a little weight was the one in the 10% solution. All the other eggs in the different solutions lost weight, even the unknown solution. According to the results the egg that was in the distilled water solution gained weight because it is the hypertonic solution. All the other eggs lost weight because they were placed in hypotonic solutions with different concentrations of sucrose. The egg that was placed in the higher concentration of sucrose lost the most weight. So, the higher the concentration of sucrose, the more water the egg lost.

This, of course, is due to the effects hypertonic state holds on the egg because there was such a high concentration of syrup outside of the egg versus the inside of the egg where there was very little. This provoked the water to move out of the egg and into the cup where the syrup

The lid was then placed on the jar and an observation was made and recorded. Observations of the egg were then made after 12 hours and 24 hours had passed and the observations were recorded. After 24 hours had passed, the egg was removed from the syrup and rinsed with tap water and observations were made and recorded.

An egg has a semi-permeable membrane, thus processes like osmosis could occur. Osmosis is the movement of water molecules from an area of higher water concentration to an area of a lower water concentration. Osmosis is important, especially for living organisms, as they help distribute nutrients in the body. An egg’s mass would change when it is soaked in different substances. The goal of this experiment was to investigate how an egg changes through osmosis. This experiment was done to show how substances affect the mass of an egg. To start off, an egg’s mass was measured by putting the egg in a beaker then placing it on a mass scale. The beaker was then filled with vinegar and left alone for twenty-four hours. After a day, the egg was taken

2.Corn syrup and the energy drink caused the egg mass change percentages of -5.8% and -1.6%, while distilled water caused an increase of 2.9%. If external environments didn’t affect internal environments, then these results would be flat. Also, after the experiment, our eggs looked plumper than before the experiment.

Diffusion and Osmosis Experiment with a Shell-Less Egg After Three days of Testing Methods with Water and Corn Syrup

In conclusion, the data that was collected helped tell us that the solutions greatly affected the cell of the egg because it caused the egg’s mass to increase than decrease. Also saw how the solutions played a role in the phospholipid bilayer and saw how it altered the shape of the egg. However, it does not support my hypothesis on the affect the egg would undergo onced placed in sugar and water but sugar was not used in this experiment, but water was used and it didn’t affect the shape of the egg, all it did was cause the egg to be in a isotonic state. According to Khan Academy (2017), states that a cell is isotonic “When the extracellular fluid has the same osmolarity as the cell, there will be no net movement in or out of the cell”. Which

Once the experiment had taken place, I realized that when I compare the acidity levels of the three liquids, the grape juice is slightly more acidic with an average of 2.92 to 3.53 compared to the 4.7 of the coffee and the 4.9-5.5 of the black tea. Because of the lower pH, the grape juice moderately softened the eggshell after just 4-5 hours of sitting in the liquid. The acids in the grape juice broke down the outer part of the eggshell which made it sort of flimsy and soft. The thin eggshell began to peel layer by layer due to not being able to hold itself together.

There was a vast difference in the impacts of the percentage of sucrose in the solution each egg was in. Because there was a higher concentration of sucrose in the syrup compared to the sucrose solution, more water moved out of the cell. This movement of water is demonstrated by the weight of each egg at the conclusion of the experiment (Figure 1). One way to continue this experiment would be to leave each egg in the given solution for a longer amount of time, say an hour. It will be beneficial to discover if each egg continues to decrease in weight. When the weight of the egg ceases to change, the dynamic equilibrium will be achieved. The time at which the dynamic equilibrium will occur can be determined by continuing the length of the
