I can not figure out how to explain this
in areas affected by acid rain, statues and structures made of limestone (calcium carbonate) often show signs of considerable deterioration

Limestone is made mostly of calcium carbonate (CaCo3) and acid rain contains H2SO4, sulfuric acid. The chemical reaction of calcium carbonate and sulfuric acid results in the dissolution of calcium carbonate, so anything made of limestone will eventually show deterioration. Even normal rainwater is slightly acidic and does the same thing to limestone, but at a much slower rate.

According to my children's elementary school science class, a way to determine if an unknown rock is limestone to pour vinegar on it. If it fizzes, the rock is limestone. We tried it and it really does work. The fizzing is the acid in the vinegar attacking the limestone. So limestone is attacked by acid. So acid rain is attacking those statues.

Acid reacts with limestone (calcium carbonate), bringing it back to near neutral.

The acid is neutralized from the limestone.
