1. Formation of Zinc Sulfate:
The primary reaction is the formation of zinc sulfate (ZnSO₄), a soluble salt. This occurs as the zinc ions (Zn²⁺) from zinc carbonate combine with the sulfate ions (SO₄²⁻) from sulfuric acid.
ZnCO₃(s) + H₂SO₄(aq) → ZnSO₄(aq) + H₂O(l) + CO₂(g)
2. Release of Carbon Dioxide Gas:
The reaction also generates carbon dioxide gas (CO₂), which is released as bubbles. This is a classic indication of a reaction between a carbonate and an acid.
3. Production of Water:
Water (H₂O) is formed as a byproduct of the reaction.
4. Heat Generation:
The reaction is exothermic, meaning it releases heat. You will likely observe the solution warming up.
5. Potential for Acidic Solution:
Depending on the initial amounts of reactants, the resulting solution may still contain some sulfuric acid, making it acidic.
Overall, the reaction between zinc carbonate and sulfuric acid produces zinc sulfate, carbon dioxide gas, water, and generates heat.
