Mandarinka [93]

Calcium sulfate, carbon dioxide, and water are produced when sulfuric acid and calcium carbonate interact.

<h3>What results from the reaction of calcium carbonate and sulfuric acid?</h3>

The insoluble in water free lime (CaCO3) interacts with sulfuric acid. It takes only a few minutes for sulfuric acid and lime to react and produce gypsum. H2SO4 + Lime CaCO3 = CaSO4 (gypsum).

<h3>What occurs when calcium and sulfuric acid are combined?</h3>

Each of these metals forms a layer of insoluble sulfate when exposed to sulfuric acid, which slows or stops the reaction altogether. A white precipitate of calcium sulfate and a small amount of hydrogen are formed in the calcium case.
