Recommended: All about osmosis

Based on the data and the recorded observations, my hypothesis is correct. When a solution is hypotonic, this causes the cell to swell, because there are more water molecules on the inside of the cell. If positive feedback continues, the cell will eventually burst. When a solution is hypertonic, this causes the cell to shrink, because there are more water molecules on the outside of the cell. Over time, the cell will start to function poorly (“Difference between Hypertonic, Hypotonic, Isotonic Solutions”). Therefore, the cell needs to maintain its internal environment through osmosis. In a hypotonic solution, osmosis allows water molecules to move from the inside of the cell to the outside, so as to keep the concentrations balanced. In a hypertonic …show more content…

Corn syrup has a very high density due to the high concentration of sugar molecules. Because the sugar molecules is too large, it cannot pass through the semipermeable membrane of the egg. As a result, only the water molecules from the egg can move to the outside. These water molecules pass through the membrane of the egg into the corn syrup until the concentration of water molecules is balanced on both sides. This is evident from the data, which states that the weight of the egg decreased from 3 to 0.5 ounces. Also, the pictures above show how the egg changed from being tight and solid to being flexible. The observations also say that the egg felt like a water balloon and was full of water inside. Overall, the egg greatly shrunk in size. Finally, when the egg was placed in corn syrup, it floated on the surface of the solution. This was because the egg floated in solutions hypertonic to its inside. This also shows how much water was transferred from the egg to the sugar solution. The higher the percentage of corn syrup was, the faster the rate of osmosis was. As a result, the egg placed in 75% corn syrup, 25% filtered water had the lightest weight (0.5 oz), while the egg placed in 25% corn syrup, 75% filtered water weighed 2 oz. Overall, the importance of this lab was to understand the process of osmosis and how it differs depending on the type of

Gummy Bear Osmosis Lab Report

1485 Words | 6 Pages

The cell membrane is semi-permeable, meaning some substances can pass through but others cannot. Osmosis is the diffusion of solvent molecules (e.g. water) across the membrane from an area of high concentration to an area of low concentration (Lopez & Hall, 2022). When the fluid on the extracellular side of the cell has a higher concentration than the cytosolic side it is hypertonic. When it is lower than the cytosolic side it is hypotonic. When both sides of the membrane have equal concentrations, they are isotonic.

Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

Corn Syrup Lab Report

Of course, the various sources of error have affected the results from this lab. Since the initial mass of eggs used was different for each group, the experimenters had to find the percent change in mass to keep the results constant. To conclude, when the eggs were placed in a corn syrup solution with more solute, their masses steadily decreased. The inside of the eggs have a lower solute concentration than the corn syrup solution outside the cell. Water within the eggs flow outwards through the membrane to the syrup solution, decreasing the solute concentration.

Differences Between Egg And Corn Syrup

135 Words | 1 Pages

The egg we experimented on went through many dramatic changes. In its original state, the circumference was 14 cm, and it was 66.8 grams in mass. However, it was much larger after it was put in the vinegar for 48 hours, the circumference was 17 cm, and the mass was 89.1 grams. This occurred because of osmosis. Since the vinegar had more water molecules than the egg, it was transferring the molecules to the egg to create equilibrium; therefore, the egg became larger.

Genius When using gas in the egg drop challenge, it spreads the amount of energy transferred from the ground to the egg. Making the energy from the ground to the egg less, because if you look closely at a balloon filled with air. When it hits the ground, the gas in the balloon spreads out inside the balloon, and then contracts back. The solid object (the egg) on top of the balloon will sink into the balloon, because it’s a solid and heavier than the gas in the balloon. Let’s say you have an egg that weighs about one pound, you have to build a sculpture that slows down something moving at 9.8 meters per second.

Osmosis Egg Lab Report Introduction The experiment revolves around selective permeability of the membranes of de-shelled chicken eggs. The eggs have been soaked in vinegar for about 3-4 days to dissolve its shells, which results in a delicate shell membrane connecting the inner contents of the egg. The shell is selectively absorbent only to water. The solution that is the dissolved in the internal contents of the egg is approximately 18-20% which is the solute concentration.

Egg Drop Lab Report

In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.

The second egg that we did, had a little buoyancy. Finally the third egg, ( last egg ) was fully floating. This taught us that a 1/2 cup of salt makes an egg float. If we put an 1/8 cup of salt, the egg did not float at all. In the end, we learned that a 1/2 cup of salt makes the egg float, but an 1/8 of a cup does not.

Osmosis Lab Report Research Question: How does the change in the concentration of a sucrose solution affect the process of osmosis in a potato cell by measuring its mass? Background information: 1 Osmosis is the process by which a liquid passes through a semi-permeable membrane, moving from an area with a high concentration of water to a low concentration of water. There are various factors that affect osmosis such as: concentration, surface area and temperature. The concentration of solutions can affect the rate of osmosis, as there is more difference in the concentration of the solutions, which means osmosis, will take place quicker. Surface area could affect osmosis based on the ease by which molecules can get through the semi-permeable

The hypothesis we came up with for this project was that in the distilled water there wouldn't be no change in the potato, we wouldn’t see a gain or loss with the water sitting in the beaker. The beaker with the 30% Sucrose and Distilled water we predicted that there was going to be weight gain to the potato. And for the distilled water with the 30% sucrose and we predicted weight loss. But the results came out to be the first bag content being isotonic the second bag came out to be hypotonic and lastly the result came out to be

Biology Design Practical Joshua Edwards What are effects of the volume of a potato and the amount of weight it loses when placed in salt solution? Introduction This design practical uses a potato’s surface area to volume ratio to see what affects it has on osmosis in different concentrations. Osmosis is the movement of water molecules through a cell membrane into an area of a higher solute concentration. The movement goes the way of the solvent with more solute because the lower solute concentration is drifting through balancing the ratio of solute per solvent (En.wikipedia.org, 2018).

Egg In Vinegar Lab Report

An egg naturally has a lot of stuff inside, so the outside solution has to be very concentrated for this to happen. That’s the case when an egg is treated with corn syrup or buried in salt. By contrast, when an egg is treated with distilled water, or a dilute salt solution, the solute concentration is higher inside the egg than out, so the water moves into the egg, increasing its mass. It may be easier to think about osmosis in terms of water concentration rather than solute concentration. If the solute concentration is high, then the water concentration will be low by comparison.
