How does acid rain affect limestone structures?

Answer 1

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.

Answer 2

because the acids in the rain, usually nitric acid or sulphuric acid, causes a chemical reaction with the calcium carbonate in the limestone. This leads to dissolution of the limestone and so the limestone buildings eventually crumble and fall down.

Answer 3

harmful as it damages it and gradually eats it away

Answer 4

Answer 5
