* Copper carbonate (CuCO₃) is a base. It reacts with acids to form a salt, water, and carbon dioxide gas.
* Sulfuric acid (H₂SO₄) is a strong acid.
When copper carbonate reacts with sulfuric acid, the following reaction takes place:
CuCO₃ (s) + H₂SO₄ (aq) → CuSO₄ (aq) + H₂O (l) + CO₂ (g)
Explanation:
1. Copper sulfate (CuSO₄) is formed as the salt.
2. Water (H₂O) is produced.
3. Carbon dioxide (CO₂) gas is released, causing effervescence.
Hydrogen gas (H₂) is not formed in this reaction. To produce hydrogen gas, you would need to react a metal that is more reactive than copper (like zinc or magnesium) with an acid.
