Osmosis Egg Diffusion

How an egg reacts during osmosis and diffusion

By : Adrianna Simovski When the egg is placed in vinegar, it will be hypotonic. When it's placed in water, it will become hypertonic. When placed in syrup, it will become hypotonic and shrink. In this experiment, we used an egg to see what happens to it during osmosis and diffusion across membranes. Throughout this week, we collected data on what happened to the egg and the mass of the egg.

During the first day, we weighted the egg and put the vinegar in the cup. Then, we let the vinegar sit on the egg for 24 hours. The next day ,day 2, we spilt out the vinegar ,and added distilled water. We also weighted the mass of the egg ,and described the appearance of the egg on the data chart.

Question 1 is, Vinegar is made of acetic acid and water. Explain how it was able to remove the calcium shell. My answer was, the acetic acid broke down the shell. Question 2 is, What happened to the size of the egg after remaining in vinegar? My answer was, After remaining in vinegar the egg got bigger. Question 3 is, Was there more or less liquid in the jar? My answer was, There was less liquid in the jar. Question 4 is, Did the water move into or out of the egg? Why? My answer was, water moved into the egg because of osmosis. Question 5 is, What happened to the egg after remaining in distilled water? My answer was, After remaining in distilled water the egg got bigger. Question 6 is, was there more or less liquid left in the jar? My answer was, there was less liquid in the jar. Question 7 is, did water move into or out of the egg? Why? My answer was, water moved into the egg because of osmosis. Question 8 is, what happened to the size of the egg after remaining in syrup? My answer was, After remaining in syrup the egg shrunk. Question 9 is, Was there more or less liquid left in the jar? My answer was, there was more liquid in the jar. Question 10 is, Did water move into or out of the egg? Why? My answer was, Water moved out of the egg because of osmosis. Question 11 is, Was the egg larger after remaining in water or vinegar? Why? My answer was, the egg was larger after vinegar because of osmosis. Question 12 is, Why are fresh vegetables sprinkled with water at markets? My answer was, so the vegetables don’t shrink down. On day 2, the eggs mass became hypertonic from the vinegar. On day 3, the eggs mass became hypertonic from the distilled water. On day 4, the eggs mass became hypotonic from the syrup. The claim that you read in the beginning of this report is false. The correct claim should look something like this: When the egg is placed in vinegar, it will be hypertonic. When it's placed in water, it will become hypertonic. When
