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.
Most eggshells contain calcium carbonate, wit h the formula CaCO3.
Eggshells are composed of approximately 95% calcium carbonate (CaCO3).
protein lined with mineral crystals like calcium or calcium carbonate
Eggshells are composed of approximately 95% calcium carbonate (CaCO3)
The principal component of eggshell is calcium carbonate.
Eggshell is calcium carbonate, CaCO3.
Egg shell is hydrated CaCO3.
Chooh
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.
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.
The calcium dissolves leaving an egg with a soft skin holding it together instead of a shell. This takes a few hours, but if you plan to test it, I recommend putting the egg in vinegar and placing it in the fridge overnight. When you wake up it will be completed.
Any strong acid, such as sulphuric, hydrochloric, nitric etc., will dissolve egg shell.
its the fact that
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.
a chemical reactions occurs between the egg shell and the vinegar.
The shell disappears because of the chemical reaction between the eggshell and the vinegar.
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.
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.

"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
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.
The reaction is:CaCO3 + 2 CH3COOH = (CH3COO)2Ca + H2O + CO2
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.
