Answer 2

Acid Rain Effects on Buildings

Acids have a corrosive effect on limestone or marble buildings or sculptures. It is well established that either wet or dry deposition of sulfur dioxide significantly increases the rate of corrosion on limestone, sandstone, and marble.

sulfur dioxide plus water makes sulfurous acid

SO2 + H2O --> H2SO3

sulfur trioxide plus water makes sulfuric acid

SO3 + H2O --> H2SO4

The sulfuric acid then further reacts with the limestone in a neutralization reaction.

Limestone: CaCO3 + H2SO4 --> CaSO4 + H2CO3

H2CO3 --> CO2 gas + H2O

The calcium sulfate is soluble in water and hence the limestone dissolves and crumbles..
