Hey mate here is your answer

CACL2

You can dissolve the shell of an egg so that the membrane is completely intact, leaving the egg “naked.” The process is simple, takes only a few days, and can easily be done using household objects. An eggshell is made up mostly of a compound called calcium carbonate which dissolves when exposed to an acid such as vinegar.
