Final answer:
Limestone neutralizes acid through chemical reactions by forming hydrogen carbonate and calcium hydrogen carbonate. Lime water can demonstrate the reaction between acids and carbonates.
Explanation:
Limestone neutralizes acid through a chemical reaction where the hydronium ion from the acid combines with the carbonate ion from calcium carbonates to form the hydrogen carbonate ion. The reaction results in the formation of calcium hydrogen carbonate, which dissolves slowly.Lime water can also be used to demonstrate the reaction of acids with carbonates, producing carbon dioxide and turning milky.
