Question

Effect of acid rain on limestone investigatory project

Answer 1

Explanation:

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.

Answer 2

Buildings, historical sites, monuments, and statues can damage by acid rain, especially those composed of calcium carbonate-rich materials like limestone.

• Any precipitation that has a high concentration of nitric and sulfuric acids is referred to as acid rain.
• In several significant urban and industrial locations, this type of pollution poses a substantial regional environmental threat.
• The gases SO₂ and NO are released into the atmosphere by cars, some industrial processes, and fossil fuel-burning electric power plants, where they react with clouds of water vapor to produce sulfuric and nitric acids.
• SO₂, an acid rain precursor, may immediately react with the calcium carbonate-rich limestone in the presence of water (H₂O) and produces gypsum as a product.
• Gypsum will eventually chip off or be dissolved by water.
• In addition, marble and limestone can be directly dissolved by acid rain.
