As they contain mainly calcium carbonate, bird eggshells dissolve in various acids, including the vinegar used in cooking. While dissolving, the calcium carbonate in an eggshell reacts with the acid to form carbon dioxide. [14]
Calcium acetate can be prepared by soaking calcium carbonate (found in eggshells, or in common carbonate rocks such as limestone or marble) or hydrated lime in vinegar: . CaCO 3 (s) + 2CH 3 COOH(aq) → Ca(CH 3 COO) 2 (aq) + H 2 O(l) + CO 2 (g)
If the eggs are marinated in the mixture for several weeks or more, the vinegar will dissolve much of the shell's calcium carbonate and penetrate the egg, making it acidic enough to inhibit the growth of bacteria and molds. [47]

Crystal structure of calcite. Calcium carbonate is a chemical compound with the chemical formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite, most notably in chalk and limestone, eggshells, gastropod shells, shellfish skeletons and pearls.
The simple reason is that "bacteria can enter eggs through cracks in the shell," most commonly salmonella. The CDC estimates that only about one in every 20,000 eggs are contaminated with salmonella.
