The chemical formula for marble is also CaCO3. This indicates that the calcium carbonate formed on whitewashed walls is chemically similar to the material of marble.
What is the chemical formula for marble, and how is it related to the reaction of slaked lime with carbon dioxide?

The chemical formula for marble is CaCO₃, indicating that it is primarily composed of calcium carbonate. In the reaction of slaked lime {Ca(OH)₂} with carbon dioxide (CO₂), calcium carbonate is formed. The chemical equation for this reaction is:
Ca(OH)₂(aq) + CO₂(g) → CaCO₃(s) + H₂O(l)
In this process, carbon dioxide reacts with slaked lime to produce calcium carbonate (marble) and water. The reaction is a part of the natural carbonation process and is involved in the formation and transformation of geological formations like limestone and marble.

The chemical formula for marble is CaCO3, representing calcium carbonate. This is the same compound formed when slaked lime (calcium hydroxide, Ca(OH)2) reacts with carbon dioxide (CO2), producing calcium carbonate (CaCO3) and water. The similarity in the chemical composition demonstrates how the reaction of slaked lime with carbon dioxide mirrors the natural process of marble formation, where calcium carbonate precipitates out of solution.
