the make up of a chicken egg is predominately CaCO_3_ when added to vinger or dilute acetic acid CH_3_CHOOH you will see bubbles form. The formed bubbles are CO_2_ gas being formed while the eggshell dissolves. the Chemical break down then becomes CO2 + H+ (H30) + CaCH3CHOO.
When an egg is placed in vinegar, the shell dissolves due to the vinegar's acidity. This causes the egg to increase in size as the vinegar penetrates the egg's membrane, causing it to swell.
When you put a raw egg into vinegar for 72 hours, the vinegar dissolves the eggshell due to its acidic nature. This process creates a chemical reaction that causes the eggshell to break down, leaving behind the membrane that holds the egg's contents intact. The egg becomes bouncy and rubbery due to osmosis, as the vinegar solution replaces the water inside the egg.
An egg swells in vinegar because of diffusion. The vinegar has seeped through the egg's membrane, which causes the egg to inflate. However, the main reason you put the egg in the vinegar is because you want to dissolve the shell. This makes diffusion easier to occur on the egg's semi-permeable membrane. When you put the egg in the vinegar for the first time, an expansion is likely due to the carbon dioxide in the shells (it's the bubbles you see). This will expand the shell as the carbon dioxide attempts to escape.
What?After two days the egg shell will start to disintegrate (dissolve) and after a week the translucent membrane and the actual egg itself will be the only thing left. It will be rubbery and wrinkled.Why?The acidic content of the vinegar reacts with the calcium carbonate in the egg shell, and dissolves it. Because vinegar is only a weak acid the process takes some time.
wow. the last answer was totally wrong. this answer is right though because i am learning about this right now :) okay well first off, the egg shell would disinagrate which is that white foamy stuff at the top. but it takes about one day to get that way. and then there will be a thin coating over the shell. i don't know the chemical equation but i do know that this is what happens. you can acually see the yolk in the egg move around. its pretty tight :) let me suggest though that you DON'T eat it. because you will or can get salamenela disease and the egg wouldn't taste that good anyways. i sure hope this helped.
a chemical reactions occurs between the egg shell and the 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.

When an egg is soaked in vinegar the vinegar reacts with the calcium carbonate of the shell by breaking it down into its simplest forms. (Calcium and carbon dioxide.) Therefore causing a chemical change.
"The presence of the acid in vinegar, forced the egg shell to soften, because of the chemical reaction of the acid and calcium carbonate in the egg shell." I edited it a little for you.
When you put vinegar in a naked egg the shell will decrease its shell then turning into a smelly egg
It should be noted that it is not the eggs that dissolve, but the egg shell, and it is not the fact that it is vinegar, just that it is an acid. Egg shells involve calcium compounds which will dissolve in acid. Vinegar is a slightly acidic compound and so it dissolves the calcium compound.
When an egg is placed in vinegar, the outer shell dissolves due to the acidic nature of the vinegar. This leaves behind a semi-permeable membrane that allows for the exchange of certain substances, resulting in a rubbery, bouncy texture due to the changes in osmotic pressure and chemical composition.
The acetic acid in vinegar will eventually dissolve the egg shell (composed from calcite, a crystalline form of calcium carbonate) away entirely. Without the hard shell, the albumin and the yolk will be held egg-shaped by the thin skin of the inner shell membrane. The inner skin membrane is between the hard outer shell and the albumin (commonly called egg white).
Well when I did my science project on this when i first I had 3/4 up of vinegar in a plastic cup put the egg into the vinegar you could see the acids from the vinegar and egg building up. On the second day, there was a lot of bubblie white stuff in the top of the plasic cup i had.
White vinegar is the best liquid for making an egg shell rubbery. The vinegar must be changed daily to prevent mold from growing on the egg shell.
The reaction is:CaCO3 + 2 CH3COOH = (CH3COO)2Ca + H2O + CO2
