Calcium carbonate - Wikipedia

The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its o

Marble - Wikipedia

Acids react with the calcium carbonate in marble, producing carbonic acid (which decomposes quickly to CO2 and H2O) and other soluble salts : CaCO3(s) + 2H (aq) → Ca (aq) + CO2(g) + H2O (l)Outdoor marble statues, gravestones, or other marble structures are damaged by acid rain whether by carbonation, sulfation or the formation of "black-crust" (accumulation of calcium sulphate, nitra

4.8: The Chemistry of Acid Rain - Chemistry LibreTexts

The damage that acid rain does to limestone and marble buildings and sculptures is due to a classic acid–base reaction. Marble and limestone both consist of calcium carbonate (CaCO 3), a salt derived from the weak acid H 2 CO 3.As we saw in Section 4.7 the reaction of a strong acid with a salt of a weak acid goes to completion. Thus we can write the
