Calcium carbonate is a base, and its chemical symbol is CaCO3. Vinegar contains water and acetic acid, which gives vinegar its sour taste. Acetic acid has a chemical formula of CH3COOH. All acids have one or more hydrogen atoms (H) because an acid is a hydrogen ion donor. When the vinegar and eggshell come into contact, they react and neutralize each other.
