Lab Report on Osmosis of an Egg

(Be sure to have paper towels handy as some eggs may squirt!)




Discussion

In my hypothesis I stated that if diffusion and osmosis across a selectively permeable membrane are related to the substance the membrane in submersed in, then an egg submersed in corn syrup will make it heavier as a result of water particles moving into the egg.

2) After 48 hours has passed, remove the egg from the vinegar solution and rinse it off gently.
3) Place the egg in a 250 mL beaker and fill with 150 mL of corn syrup and 50 mL of water.

The results of the experiment show the reduction in mass of the egg when soaked in syrup i.e. from T0 to T48. However, the volume of the egg increases when the egg is submerged in distilled water i.e. from T60 to T72. This is explained by the fact that when syrup is compared to the egg, syrup has a higher concentration as compared to the egg. As the theory of osmosis dictates, solutes will move from a region of low concentration to a region of higher concentration. For this reason, the mass of the egg continued to decrease as the time decreases.

Osmosis through the Cell Membrane of an Egg.

Traditionally, teachers use proof-of-concept experiments to demonstrate osmosis (e.g., grapes, chicken eggs, Elodea cells or dialysis tubing placed in hypertonic and hypotonic solutions). These experiments tend to be like cookbooks where, if students follow the steps, they will get the expected results. There is little to analyze and not much scientific process involved. Here we provide two versions of a proof-of-concept osmosis lab that can be done with the microscope (red onion and Elodea cells), along with suggestions for how students can use the methods learned in these labs to investigate their own original research questions. For example, they might compare different concentrations of salt or different types of solute (e.g., glucose, sucrose, fructose), or they could vary the temperature. For their data, they can take digital photos and measure the size of the cytoplasm before and after each treatment. Thus, rather than simply watching cells swell or shrink (an impressive, but subjective type of data), students will generate objective, quantifiable data that can be analyzed using Excel or statistics software.

Background If an egg is put into a corn syrup solution, then the egg will shrivel and become lighter because this is a hypertonic solution (the syrup) and water molecules will exit the egg due to osmosis Hypothesis (1) If an egg is put into a tap water solution, then the egg will swell up and become heavier because this is a hypotonic solution (the water) and water molecules will enter the egg due to osmosis Hypothesis (2) Will water go in or out of a chicken egg?
