Question
+ Acid Rain: Effect on Solubility of Calcium Carbonate
The chief compound in marble is CaCO3. Marble has been widely used
for statues and ornamental work on buildings, including such structures as
the Taj Mahal (Figure 1). However, marble is readily attacked by acids via
the following reaction.
CaCO3(s) + H+ (aq) = Ca²+ (aq) + HCO3(aq)
