Osmosis Is The Outer Layer Of A Solvent

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

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.

By definition, osmosis is the diffusion of water across a selectively permeable membrane in response to gradients of concentration, pressure, or temperature (G. Audesirk, T. Audesirk, B. Byers). Diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration (Diffusion). In the experiment, osmosis and diffusion occurred where the results indicated a change in mass when the egg was placed in different concentrations of corn syrup solution. My hypothesis stated that if the concentration of the solute is lower than the solvent, then the egg will shrink in size. With a majority of the results decreasing in weight, my hypothesis was proven to be correct.

In order to study the transfer of liquid across the plasma membrane, in this experiment a de-mineralized egg was examined. Upon receiving the eggs they had already previously been soaked in a vinegar solution for several days, dissolving the eggs shells thus leaving a thin semi-permeable membrane exposed, which is representative of the cells in our bodies.

Day 3 of the lab after the newly shell-less eggs had been submerged into the distilled water or syrup, we observed very different

Did the egg permeate the corn syrup (hypertonic solution) or the water (hypotonic solution)? First, using the triple beam balance we measured the mass of our egg which was 65 grams. Then, we put the egg in a 200ml of vinegar to completely take the outer shell off. The next day, after rinsing the egg, using a beaker we poured 200 ml of corn syrup into the beaker. Then put our egg into the beaker and let it sit for 24 hours. After the 24 hours, the egg has shriveled and has gone down to 48 grams. On day 3, we poured 200 ML of water into the beaker then placed the egg into the water. the next day, the mass of the egg went above the original mass of the egg at 96 grams. The egg permeated the water because of osmosis and it’s density.

Title Osmosis : How Water Diffuses Introduction The plasma membrane, the outside barrier of the cell is selectively permeable, allowing certain substances to cross more easily than others. When a cell is put in a solution, passive transport, diffusion, and osmosis occurs. During passive transport, diffusion of a substance takes place across a membrane without energy contribution, because of diffusion, the tendency for molecules to spread out. Net movement allows substances to move in one direction.

After the 24 hour period we came back to find an egg without shell. It had dissolved and left a rubber, bouncy ball like shaped egg. This is because the acidity of the vinegar mixed with the calcium of the eggshell to dissolve it and the water of the vinegar traveled through the membrane of the egg causing it to fill and resemble osmosis. After analyzing the results of the vinegar we rinsed the beaker and filled it with 150 mL of corn syrup. We placed the egg in the beaker and set it for another 24 hours. The next day we came back to discover a shrunken egg. This is because corn syrup hypertonic has a lower concentration of water than the egg therefore the water from the egg moves through the membrane and into the corn syrup to equalize the concentration. After looking at these results we cleaned the beaker and filled it with water. We placed the egg in the water and left for the final 24 hours. When we came back to look at the final results of the lab we found the egg had expanded and filled back up to about its original size. This is because the water is hypotonic and the egg has less water concentration than the water. Therefore the water molecules move into the egg instead of

Osmosis is the transfer of water molecules from places where there is a lot of water molecules to places there are not many water molecules. When the cell is selectively permeable it allows certain substances in and out of the cell. There are three terms for the amount of solute in a cell isotonic, hypotonic, and hypertonic. Isotonic means there is a balance of solute inside and outside of the cell. Hypotonic is when there is lower concentration of solute in the cell than the concentration outside of the cell. Hypertonic means there is a more solute in the cell than outside of the cell. The molecules want to reach equilibrium, or balance out the amount of water inside and outside the cell. In this alcohol investigation, the purpose was to

Results showed eggs in lower percentage of sucrose, like 0% and 10%, gained weight while the eggs soaked in the higher percentage levels of sucrose, 20%, 30%, 40%, and unknown, lost weight throughout the hour. This concluded that the chicken eggs in 0% and 10% were hypotonic, while the rest were hypertonic. Introduction

The purpose of this experiment was to observe the effects of different substances to an egg. When the egg’s mass increased by 11.58 grams after it was left submerged in vinegar, one could say that the vinegar is hypotonic to the egg since it was absorbed, thus increasing the mass. A solution is hypotonic when water concentration is higher outside the cell. The egg was somewhat depleted after it was left with corn syrup which could say that the corn syrup was hypertonic to the egg because it caused water to flow out from the egg thus decreasing the egg’s mass. A hypertonic solution has a higher water concentration inside the cell than outside. The colored water was hypotonic to the egg as well since it doubled the mass of the egg when the water

In my hypothesis, I thought the egg in water will do nothing and I think the Egg in syrup will get smaller. I was partially correct in this case, yes, the egg in syrup getting smaller was correct but the egg in water was where I was wrong. The egg in water still got bigger. So in this experiment, our egg in syrup got smaller, wrinkled and got brown and the egg in the water got bigger and bloated. So since our egg’s membrane is semipermeable it let the vinegar and water pass through, this happened through osmosis. But when we put our egg in the table syrup it shrank, how did this happen? Well since the syrup is a hypertonic solution there is an imbalance of molecules resulting in the water in the egg going through the egg because osmosis to

When the 4 eggs were weighed it was found that out of the 4 solutions, 2 were hypotonic and 2 were hypertonic. The mass of 2 of the eggs increased and the other 2 decreased after 60 minutes in the various solutions. Out of the 4, the most hypotonic solution was the distilled water; and the most hypertonic solution was the solution with 2.0M glucose. The

The purpose of this lab is to determine how the egg changes when it was in different substances which were distilled water and corn syrup. The reason the eggs change in size is because of osmosis. Osmosis is a form of facilitated diffusion when water moves through channels, water is moving from high to low. There are three types of solutions, isotonic, hypertonic and hypotonic. When the egg is placed in an isotonic solution the egg will stay the same size. Isotonic is when the concentration of water is the same outside and inside the cell and water moves equally in both directions. When an egg is placed in hypertonic solution the egg will grow because hypertonic is when the concentration of water is higher outside the cell than inside. When an egg is placed in a hypertonic solution the egg will shrink because hypertonic is when the concentration of water is higher outside the cell than inside the cell.
