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)
an egg's shell doesn't dissolve in water because the shell is to hard to dissolve in non-acid liquids.
eat them
no
Acid does because it does.
acetic acid
Yes Egg shell is made from calcium and the hydrochloric acid that the stomach produces wil rapidly dissolve it.
put it in vinegar
Vinegar would dissolve just the shell, I don't know what lemon and lime juice do.
Yes. Even dilute acetic acid, vinegar, can dissolve eggshell. Try this experiment: put a raw egg in vinegar for three days. The shell will dissolve but the egg will still be intact in its membrane. You can remove the egg and it will be rubbery. Handle delicately - the membrane is thin and easily torn. You'll also notice that the egg has swollen - the membrane is permeable, and the vinegar will penetrate into the fluid parts of the egg, swelling it.
Vinegar will dissolve the egg shell. Salt water will not do anything.
place it in a bowl of vinegar and the shell will dissolve separating the shell which is now dissolved and the egg which is still being held in the membrane
Yes. The vinegar helps dissolve the shell surface, giving way to the membrane underneath that makes the egg "bouncy."
