Chemical Properties of Limestone:

  • Chemical Formula: The primary chemical component of limestone is calcium carbonate, which has the chemical formula CaCO₃.

  • Reaction with Hydrochloric Acid: Limestone reacts with hydrochloric acid (HCl) to produce carbon dioxide gas (CO₂), water (H₂O), and calcium chloride (CaCl₂). This reaction results in the formation of bubbles or fizzing, which indicates the release of CO₂ gas.

  • Magnetic Properties: Limestone is generally not magnetic. It does not exhibit any magnetic properties and does not respond to a magnet.

Overall, limestone is characterized by its calcium carbonate composition, its effervescence when exposed to hydrochloric acid, and its lack of magnetic behavior.
