Chemical Properties of Limestone

  • Chemical Formula: The chemical formula for limestone is primarily Calcium Carbonate (CaCO₃).

  • Reaction with Hydrochloric Acid: Limestone reacts with hydrochloric acid (HCl) by producing carbon dioxide gas (CO₂), which can be observed as bubbles forming in the solution. The reaction can be represented as follows:

    \[ CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂ ↑ \]

  • Magnetic Properties: Limestone is generally not magnetic. It does not exhibit any ferromagnetic characteristics.

  • Solubility: Limestone is moderately soluble in water, especially in the presence of carbon dioxide, which forms carbonic acid that can dissolve limestone over time.

  • Other Reactions: When exposed to acids, limestone behaves predictably, reinforcing its classification as a sedimentary rock composed mainly of calcium carbonate.
