Sulfuric Acid and Calcium Carbonate
H2SO4 + CaCO3 → CaSO4 + H2O + CO2
Genel Bakış
Sulfuric acid reacts with calcium carbonate to form calcium sulfate, water, and carbon dioxide. Unlike HCl, this reaction can be self-limiting because the insoluble calcium sulfate coats the limestone surface, slowing further reaction. This is why HCl is preferred over H₂SO₄ for dissolving limestone.
