Rock: LIMESTONE

Things you might include: What is its chemical formula? Does it react to hydrochloric acid, HCl, by forming bubbles in HCl? You also might include if the rock or mineral is magnetic.
You may use bullet points or complete sentences.
If you use complete sentences, remember to use capitalization and punctuation, good grammar and spelling, etc.

Chemical Properties of Limestone:

  • Chemical Formula: The chemical formula of limestone is primarily CaCO₃, which stands for calcium carbonate.

  • Reaction with Hydrochloric Acid: Limestone reacts with hydrochloric acid (HCl) by producing bubbles of carbon dioxide gas (CO₂). This reaction can be observed as effervescence when HCl is applied to a piece of limestone.

  • Magnetic Properties: Limestone is generally not magnetic. It does not exhibit magnetic properties under normal conditions.

  • Additional Notes: Limestone may contain impurities or a mixture of other minerals, which could potentially affect its reactivity and overall properties. However, pure calcium carbonate is the primary component responsible for its characteristic reactions.
