Egg Osmosis Lab Report
Introduction
This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs, and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs, then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs, again the volume was measured and recorded. I then compared the three volume measurements and provided observation. The next experiment was to determine the effects of salt concentration on bacterial growth. The tubes of broth were labeled as directed and …show more content…
Start with a graduated beaker, or some other container marked at known volume levels. Fill the beaker or measuring cup to 200 ml with water.
2. Set that measuring device aside for later.
3. Then get a cup and place the raw egg in the cup and fill it with vinegar until the egg is covered. Let sit in vinegar for 24 hrs.
4. After soaking for 24 hrs remove the egg and rinse with water to remove any remainder of the egg shell.
5. Place egg in the designated cup with water and measure volume.
6. Record the starting volume of the egg (final volume)-(starting volume)=egg volume.
7. Then place the egg in another cup and fill it with corn syrup until egg is covered. Let sit for 24 hrs.
8. After soaking for 24 hrs remove the egg and rinse with water.
9. Place egg in the designated cup with water in it and measure volume and record volume.
10. Then place the egg in another cup and fill with water until egg is covered. Let sit for 24 hrs.
11. After soaking remove the egg and place in the designated cup with water and measure and record volume
12. Compare the three volume measurements.
Results
The vinegar resolved the shell of the egg and some of the vinegar when into the egg by osmosis. The egg was bigger and really slimy and had no
