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.

Acetic Acid will dissolve the outer shell of an egg.

If you soak a raw egg in acetic acid the eggshell will have dissolved usually within 24 hours. Almost immediately the release of CO2 can be seen and illustrated to students. Within 24 hours the eggshell can be literally washed off. After the first 2-4 hours the shell composite will break down into a fibrous mixture, some of which will be ejected from the shell and can be seen in that state under a microscope. In about 48 hours, if you leave the egg, the consistancy of the remaing egg shell takes on a lumpy texture under the microscope and leaves you with a bouncing rubber egg.

When put into vinegar the shell will dissolve slowly. This is the vinegar's acetic acid, which will dissolve much of the shell's calcium carbonate.
