acetic acid
an egg's shell doesn't dissolve in water because the shell is to hard to dissolve in non-acid liquids.
Yes. The vinegar helps dissolve the shell surface, giving way to the membrane underneath that makes the egg "bouncy."
no
The egg shell might be too dense to dissolve. It probrobly will dissolve eventually, but I don't really know. (Dense means how closely the atoms are compacted together)
The calcium that makes the egg shell makes it hard.
Acid does because it does.
Yes Egg shell is made from calcium and the hydrochloric acid that the stomach produces wil rapidly dissolve it.
put it in vinegar
the shell shape makes it strong.
An eggshell dissolves faster in acids like vinegar because the acidic environment breaks down the calcium carbonate in the shell. The reaction between the acid and the shell increases the speed of dissolution.
Vinegar will dissolve the egg shell. Salt water will not do anything.
