Answer:
Dilute HCl dissolves eggshells.
Eggshells are rich in calcium carbonate (CaCO₃) which when treated with dilute hydrochloric acid (HCl), carbon dioxide (CO₂) gas is produced as,
2HCl + CaCO₃ ⇒ CaCl₂ + H₂O + CO₂↑
Thus, the above chemical reaction shows that CaCO₃ dissolves completely when treated with dil. HCl.
