Does vinegar have the same water concentration as an egg?
No, vinegar has a higher concentration of water than an egg. Therefore, if an egg is placed in vinegar, then it will gain mass because vinegar is hypotonic to the egg.
When the vinegar absorbed into the egg and caused it to expand This was an example of?
Osmosis. The egg is hypertonic and the vinegar is hypotonic.
Sperm and egg cells result from a special type of cell division called?
Sperm and egg cells are the result of meiosis.
How does osmosis occur in an egg cell?
Osmosis occurs in an egg cell if you place it in liquids. If you put it in vinegar, the egg's shell will start to dissolve. Then, you can test osmosis in water or salt water. Because the egg is considered a cell, it will swell the egg cell with plain water (meaning it will increase the egg's mass). With salt water, the egg cell will shrink in mass.

How is osmosis similar to this process?Prior Knowledge: What did/do I already know about the topic that is relevant to this lab? I already know that osmosis is the way that cells can get the things that they need from materials outside of the cell such as food and nutrients. Cells can also use osmosis to get rid of waste and unwanted materials and send them to the places outside of a cell. I also knew that we have an ordinary egg that we are placing in different acids that will affect the egg in some way. These acids are vinegar, corn syrup, and water with dye. All of these materials contain different amounts of H20, which affects the structure of the egg in different ways. Vinegar has 95% H20 and corn syrup has 5% H20.Hypothesis: Vinegar; if I soak the egg in nucleic acid (vinegar) for one to two days, then the acid would eventually weaken the egg after the shell resisted it. Corn Syrup; if I soak the egg in corn syrup then the rest of the membrane will dissolve while trying to keep the corn syrup out. Water with Food Coloring; if I soak the egg in water with food coloring then it will inflate back to its original size.Variables: Manipulated/Independent: As the scientist, I am changing the different types of acids or liquids that I submerge the egg in. These solutions that we used include vinegar, corn syrup, and water with dye. This controls what happens to the egg and forms our experiment.Responding /Dependent: We are measuring how the egg has changed during this experiment. The egg has changed in mass and circumference because of what the acids and other liquids did to the egg.Controlled: We should use the same size egg, the same time that the egg is submerged in the liquids, the amount of liquid and how much the egg is submerged into the liquid, use the same egg throughout the experiment, and measure it the same way (by centimeters and grams).Materials: Some materials that you need to complete this lab are a plastic cup to keep the egg in, vinegar (white vinegar) for the first procedure, corn syrup (light corn syrup) for the second, and food coloring for the third. You will need an egg, a string to measure the circumference of the egg, a ruler, a scale, and water to wash out the egg after each procedure.Step-By-Step Procedure:Step 1- First, you take an egg (any size) and carefully observe it. This is important because you need to be able to see what the egg looks like before you perform the experiment, which will change the size and shape of the egg.Step 2- You will need to measure the circumference of the egg and the mass so you will be able to see the effect that the solutions have on the egg. Wrap a string around the egg to measure the circumference, and measure the cup before the cup with the egg inside, so you can find the exact mass of the egg.Step 3- Once you have fully observed the egg, then you will need to completely submerge the egg in vinegar. After that, you wait for about a day for the acid to make an impact on the egg.Step 4- The next day, when you find the egg, something about it might have changed. Before you remove the egg from the vinegar, observe the changes of the egg. Does it look smaller or bigger? What caused the change to happen?Step 5- Then, carefully (the egg is weaker, it might break) rinse the egg and cup in warm water so that it doesn't harm the egg, and be sure to get rid of all of the vinegar.Step 6- Then measure the circumference and mass again, and record any more observations. Was there a difference between how it was the day before? Think about what you think will happen next when you add the corn syrup.Step 7- Next, completely cover the egg with corn syrup. Wait about a day, take your cup, and record any changes.Step 8- This time, when rinsing the egg out, be very careful because it is very weak now. Measure the mass and the circumference and record more observations. Now think about how the egg has changed throughout the entire experiment. What do you think will happen next?Step 9- Then add the water with food coloring, and wait for another day.Step 10- The next day, pick up the cup again and record any changes with the egg, rinse, record the mass and circumference, and make a note of any other changes. This time, don't add any liquid and let it sit overnight. What will happen now?Conclusion: My hypotheses were "Vinegar; if I soak the egg in nucleic acid (vinegar) for one to two days, then the acid would eventually weaken the egg after the shell resisted it. Corn Syrup; if I soak the egg in corn syrup then the rest of the membrane will dissolve while trying to keep the corn syrup out. Water with Food Coloring; if I soak the egg in water with food coloring then it will inflate back to its original size." All of my hypotheses are supported. The first hypothesis that I made involving the vinegar was supported because the acid did weaken the egg by wearing away the shell and making it translucent. Because of osmosis, the shell of the egg resisted the substance that would cause harm to the egg but the egg still weakened. My second hypothesis involving the corn syrup was supported because the rest of the shell did dissolve leaving no trace of the white layer. The corn syrup caused the egg to become very weak and deflated. My third hypothesis involving the water with food coloring was supported because the egg did inflate back up. As an analysis of my data, throughout the experiment, the egg shrunk and grew and had different sizes after each material was added. On November 10, when we began the experimental process, the egg's mass was 58 grams and its circumference was 15cm. At this point, the egg hadn't been soaked in a solvent yet. The next day after we had soaked the egg in vinegar the egg seemed to have gotten bigger and the shell had worn away. The egg had a mass of 61 grams and a circumference of 15cm. The difference between the mass of the egg the day before the vinegar was 3 grams and the difference of the circumference was .8cm. The day after we added the corn syrup, the egg shriveled up. It's mass was only 40 grams and its circumference was only 13cm. The difference of the mass was 21 grams and the difference of the circumference was .8cm. The following day, after we added the water with dye, we noticed that the egg had gotten larger and had inflated again. The mass was a huge 80 grams and the circumference was 17cm. The difference of the mass was 40 grams and the difference of the circumference was 2cm. Throughout the whole experiment, osmosis caused the egg to shrink and grow. Finally, we have learned that osmosis lets good materials into the membrane (shell)and prevents and lets out harmful substances.Possible Sources of Error: Discuss anything that might have interfered with your experiment. Explain how these impacted the outcome and what changes could be made in future experiments. We might have made a measuring error when measuring the mass and circumference of the egg. This error would have made there be either a more or less difference between the eggs in the different solvents. This error would have affected the data making it inaccurate. There could have been a small crack in the egg, causing the substance that is inside of the egg leak and make the mass incorrect. If enough of the substance leaked out, the circumference could have changed when the egg shrunk. And the solution (vinegar, corn syrup, and water with dye) might have entered the egg easier. Another possible error that we may have made is we could have caused harm to the egg by holding it wrong or not being gentle enough and causing damage.
How do you prevent the white from spreading when poaching an egg?
The white spreads only when there is not enough vinegar. The more vinegar in the poaching water, the better result the egg will not spread the white.
How do you get an egg to float in vinegar?
To make an egg float in vinegar, you simply have to make the vinegar denser than the egg. Its like when you mix oil and water together, if you leave it for a while, you notice that they separate, one on top of another. The substance at the bottom is more dense than the substance at the top. To recreate this with vinegar and an egg, add salt to make the vinegar denser, and then put the egg in. If the egg still sinks, add more salt. Repeat until you get your desired result.
Does vinegar have the same water concentration as an egg?
No, vinegar has a higher concentration of water than an egg. Therefore, if an egg is placed in vinegar, then it will gain mass because vinegar is hypotonic to the egg.
Why does an egg fold if you put it in vinegar?
Why does an egg fold if you put it in vinegar?
Why does a egg go bouncy when you put it in vinegar?
The vinegar makes the egg soft because, the vinegar has a chemical reaction due to the Carbon Dioxide in the vinegar which has an effect on the egg. That's why the egg's shell dissolves off, and the egg gets soft.Correction:A raw egg will NOT bounce when dropped into vinegar. The egg must sit in vinegar for about 24 hours, so that the vinegar will react with the carbon dioxide in the egg shell, before the egg will become soft and rubbery. See link below.
Why does the egg have a equal mass when added to vinegar?
The vinegar isn't absorbed by the egg.
What do you think vinegar or salt water will break a egg?
The egg will break in vinegar.
Why does vinegar make eggs soft?
The vinegar makes the egg soft because, the vinegar has a chemical reaction due to the Carbon Dioxide in the vinegar which has an effect on the egg. That's why the egg's shell dissolves off, and the egg gets soft.
What is the circumference if you put an egg in vinegar?
The circumference of an egg in vinegar varies for each egg.
Can you use vinegar as an egg replacer for baking?
Vinegar would do nothing to replace an egg.
What happens when you put a raw egg in vinegar and then saltwater?
The vinegar will disintegrate the egg shell and the salt will suck out all the water and shrivel the egg.
How many millimeters is a egg after being in vinegar?
Because vinegar will dissolve the calcium shell of an egg, the egg will increase in size by about 30 to 60 millimeters after being in vinegar.
