Eggshells are calcium carbonate. The acetic acid in vinegar attacks the carbonate, releasing carbon dioxide gas and leaving calcium acetate, which is soluble. Other examples of this include calcium deposits from hard water, pearls, and bones.
The calcium carbonate in the eggshell has a pH of around 9, which chemically makes it a base. The acetic acid in the vinegar has a pH of around 2.4, which makes it an acid. When the two come in contact, a chemical reaction happens, and the changes happen as listed earlier.

∙ 12y agoIt is the vinegar that disolves the eggshell. The baking soda would be considered inert. Baking soda is sodium bicarbonate, while eggshell is primarily calcium carbonate. Two substances which don't react. Vinegar is acetic which reacts with calcium carbonate, essentially rendering the shell into carbon dioxide as a biproduct. It can take up to 24 hours for this result to complete depending upon the acidity of the vinegar. Any acedic acid can be used for this (i.e. lemon, lime or Orange Juice), but times may vary depending upon the the strength of the acid used.

∙ 15y agothe eggshell absorbs the vinigar and the it gets all muchy after left in a cup of vinigar. you shud tryn experiment with it; its kool ;)

∙ 13y agoAs vinegar is acidic and dissolves the egg shell
Sorry if I'm not right. First time answering.

∙ 12y agoIt takes about 3-5 hours for vinegar to dissolve an egg shell.However the time depends on the pH of the vinegar and the thickness of the (calcium carbonate) egg shell.

What makes an eggs shell dissolve fast?
If you put a fresh uncooked egg into vinegar the hard shell will dissolve leaving just the soft membrane.
What in the vinegar makes the egg shell dissolve?
acetic acid
What other liqud besides vinegar will dissolve an egg shell?
Any strong acid, such as sulphuric, hydrochloric, nitric etc., will dissolve egg shell.
What info are you looking for if you are trying to dissolve an egg shell?
put it in vinegar
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.
How egg explode?
An egg will explode by vinegar. Vinegar will also dissolve an egg shell leaving the egg to not only feel, but also look like rubber.
Why vinegar can be used for colouring egg?
Vinegar is acidic. An acid will dissolve (partially at least) the calcium of the shell.
Do you leave the shell on the egg before you put vinegar on it to make it a bouncy egg?
Yes. The vinegar helps dissolve the shell surface, giving way to the membrane underneath that makes the egg "bouncy."
What happens when you put a peeled egg in vinegar?
If it is already boiled nothing will really happen except vinegar eating it up. If it was a raw egg with the shell intact, the vinegar will dissolve the shell and you can watch the proteins get denatured.
What do you think vinger or salt water will breack a egg?
Vinegar will dissolve the egg shell. Salt water will not do anything.
How long does it take to dissolve an egg shell in vinegar?
yes egg shells can disintegrate in vinegar.
What happen to egg RAW when you put into vinegar in 72 hours?
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.
