Product of CaCO3+H2SO4

CaCO₃ (aq)  +  H₂SO₄ (aq) →  H₂CO₃(aq)  +  CaSO₄(s) ↓

Explanation:

Aqueous solutions of CaCO₃ and H₂SO₄ can be mixed to form, two products, the calcium sulfate and carbonic acid.

In order the find the products, we can dissociate the reactants:

CaCO₃ → Ca²⁺  +  CO₃⁻²

H₂SO₄ → 2H⁺  +  SO₄⁻²

So, the protons will be catch by the carbonate and the calcium will form a precipitate with the sulfate. As Ca is an element from group 2, remember that sulfates can make precipitate with these elements (Ca, Ba and Mg)

Ca²⁺  +  SO₄⁻²  → CaSO₄

2H⁺  +  CO₃⁻²  ⇄  H₂CO₃   (Carbonic acid is a weak one, so in the reaction we add two arrows, because it is an equilibrium acid/base)

We add the phases to the main reaction:

CaCO₃ (aq)  +  H₂SO₄ (aq) →  H₂CO₃(aq)  +  CaSO₄(s) ↓

the formula would be mgso4
