The shell of the egg is made up of calcium carbonate. The acidic vinegar eats the outer shell and inner membrane is left, giving you the feeling of rubber. The outer shell is dissolved in the vinegar.
Actually to understand this, it is important to know what substances are involved in the reaction. Vinegar contains about 3% acetic acid and the substance that gives strength to an eggshell and is calcium carbonate. If you remember from your chemistry class, acids react with calcium carbonate to give off carbon dioxide and a calcium compound.
So, the reaction between vinegar and eggshell is:
CaCO3 (s) + 2H+ (aq) ----> Ca2+ (aq) +H2O (l) + CO2 (g)
When you put the eggshell into vinegar, you will see bubbles form. This are actually carbon dioxide given off. The calcium from calcium carbonate converts into calcium acetate which is somewhat soluble. Eventually most of the calcium carbonate is converted into carbon dioxide and acetate. As this calcium carbonate is extracted from the eggshell, all that is left behind is a skeleton of the other substances present in the eggshell matrix. This feels like rubber.
This is done by when an egg is 95% of calcium carbonate and vinegar is a dilute acetic acid; the shell is reacting to the acid and leaves salt, water , and carbon dioxide. The formula for that whole interaction is “2 CH3COOH + CaCO3 --> (CH3COO)2Ca + CO2 +H2O.”
Eggs contain something called "calcium carbonate". This is what makes them hard.
Vinegar is an acid known as acetic acid. When the egg and the vinegar combine, a chemical reaction takes place and a gas called carbon dioxide is released. This is what the bubbles are made of. The chemical reaction keeps happening until all of the carbon dioxide in the egg is used up. The egg shell has many tiny microscopic holes in it, allowing the vinegar to pass through the eggshell, this is called osmosis. When you take the egg out of the vinegar it's soft because all of the carbon dioxide when it floats out of the egg in little bubbles. If you shake the egg, you can see the yolk sloshing around in the egg. Its shell will become a material that feels like a rubber ball. After a period of about 4 weeks the egg will become bouncy.
You guys are all wrong. The eggs shell is made of calcium when the egg is put in to vinegar the acids eat away at it. It becomes rubbery and shows the inner membrane.
It doesn't turn into rubber it's eggshell is just dissolved by the vinegar.the vinegar has acetic acid and a egg is made up of calcium carbonate.the vinegar is just attacking the eggshell and eating it leaving the eggshell's membrance.
No, No, No, No, No, No, No! These answers are all incorrect! What happens to an eggshell when placed in vinegar is a process called Osmosis. Osmosis is when water diffuses through a cell membrane, and to an egg, the shell is it's cell membrane! When you pick the egg up, it may feel rubbery, but by all means, DO NOT BOUNCE THE EGG! The shell is still very very fragile! It may become see-through depending on the vinegar you use. Please, from a person who has done the experiment, listen to this information. It will lead you in the correct direction. And If you drop that egg, boy it will smell so badly. Trust me.
It will soften and eventually totally remove the hard outer shell. When the shell is completely dissolved, you will be able to view the the insides of the egg through the remaining clear membrane.
A trick that we used to pull was to soak the egg until pliable and then roll it into a cigar shape, making it thin enough to slide into a soda bottle. After putting it into the bottle rinse the in cool water and the egg will return to its normal shape. Dump the water and in a couple of days the shell will reharden and you have egg in a bottle. If you are not seeing the egg soften it might be because the vinegar is old and has lost its potency.
While the egg may look like rubber, it is not actually rubber nor does it turn to rubber. Vinegar is harsh and will eventually penetrate the shell, eventually dissolving it.
I did this experiment in school, it is because when the egg is in vinegar for period of time, the vinegar eats away at the calcium in the shell and eventually the shell disappears. When this happens the egg is only surrounded by the membrane in which at this time it is very delicate.
The outer shell will become rubbery and bouncy.
The calcium carbonate in the egg dissolves into the vinegar. I did this trick as a science demo for elementary school kids when I introduced a unit on rocks. Calcium carbonate (calcite) is also found in limestone.
The vinegar dosent turn it into rubber it just feels like it, because the vinegar eats away the shell.
No not really but after 72 hours the shell some off and the skin is just there great for a science project
It will not turn to rubber, it will just dissolve the chemical composition of the egg shell leaving the protective membrane encasing the the egg
It doesn't turn to rubber. Fresh vinegar will dissolve the calcium from the the eggshell.
As a side note, you can peel the shells from hard-boiled eggs and put them into left-over pickle-juice (vinegar) to preserve them (pickled egg!) and the juice will tint them slightly. If you eat ham, you can later be amused by your own meal of "Green Eggs & Ham".
It takes a week or so for it to acquire the color. If good sanitary methods are used, it lasts at least a year. It's "pickled". It's just a little tart. I dislike eggs pickled in beet juice.
Does an egg turn to rubber if put in vinegar?
They don't turn to rubber, they just get softer. Just as paper gets soggy in water or your cereal gets soggy in milk.
The egg becomes rubbery and will float to the top. There is a chemical reaction going on because of the bubbles clinging to the egg.
It turns red if you leave it for 3 months
No because mole will start to form
The PH of vinegar can compound an egg shell.
Its going to work it takes 21 days then you cando what ever to it
The shells come off and you see the membrane and it changes to orange. Isn't it cool
I want to now more about the rubber egg show me more more about the rubber egg
Was the egg kept in the refrigerator or left out at room temperature? Egg shells dissolve in vinegar due to the acidic value of vinegar and the shell being of a calcium material. If kept in the refrigerator, you then would be able to see the egg membrane almost like a see through type egg. This takes about 24 hours though. 2 weeks, I am guessing that if left in the fridge, the vinegar will penetrate the membrane as well and solidify the egg.
If you mean soaking a raw egg (still in its shell) then I don't know, but if you soak a shelled, hard boiled egg in vinegar for long enough, you get pickled eggs which I think are delicious, especially with a bag of crisps (chips , if you are in the US).
The egg become sticky put into the vinegar
What is it called when you put an egg in vinegar,and it sheds it shell?
It doesn't really turn into rubber, but it does take on a consistency like rubber. Hard boil it instead of just soaking it, it's much quicker.
The egg will become rubbery. After 3 days the shell will start to come off and you will be able to see orange. This is a slow process. This is my 4th day and only a small amount has come off.
WARNING: THE EGG YOU PUT IN VINEGAR WILL START TO SMELL. IF YOU ARE IN WINTER, IT WOULD BE HELPFUL TO PUT IT OUTSIDE TO FREEZE AND THROW AWAY AFTER IT IS FROZEN.
The egg will be soft and smelly and will bounce if you drop it.
The egg shell turns like rubber like if its boiled
The egg shell dissolve and the insides become rubbery.
No it will not turn to rubber it will just stay as a egg x
Makes it kind of rubbery/bendy if you soak a whole egg in vinegar you can push it into a milk bottle, but I can't remember how long you soak it for, I think about 10 days.
The vinegar dissolve the egg shell and make the inner egg freeze
Yes I'm doing it too cool
How long does it take for an egg to float in vinegar
What happens when you boil down the vinegar-eggshell solution? Pure calcium?
It will turn into vinegar?
I think it will break down
