* Calcium sulfate (CaSO₄): This is a white solid, also known as gypsum.
* Carbon dioxide (CO₂): This is a colorless and odorless gas.
* Water (H₂O): This is a liquid.
The balanced chemical equation for this reaction is:
CaCO₃(s) + H₂SO₄(aq) → CaSO₄(s) + CO₂(g) + H₂O(l)
Here's a breakdown of what happens:
* The sulfuric acid (H₂SO₄) reacts with the calcium carbonate (CaCO₃) to form calcium sulfate (CaSO₄).
* The hydrogen ions (H⁺) from the sulfuric acid react with the carbonate ions (CO₃²⁻) from the calcium carbonate, producing carbonic acid (H₂CO₃).
* Carbonic acid is unstable and quickly decomposes into carbon dioxide (CO₂) and water (H₂O).
This reaction is an example of a double displacement reaction, where the positive and negative ions of the reactants switch places. It's also an example of an acid-base reaction, where the acid (H₂SO₄) reacts with the base (CaCO₃) to produce salt (CaSO₄) and water (H₂O).
