Question

effect of acid rain on monuments​

Answer 1

Acid rain can damage buildings, historic monuments, and statues, especially those made of rocks, such as limestone and marble, that contain large amounts of calcium carbonate. Acids in the rain react with the calcium compounds in the stones to create gypsum, which then flakes off.

Answer 2

$\huge\bf{Answer :}$

• The amount of acid in the acid rain chemically reacts with compounds of calcium in order to produce the compound gypsum.
• The acid rain targets those monuments which are being constructed from the rocks and the monuments that have substances like limestones and marbles.
• Inside Marbles and limestones, there are chemical compounds which are called calcium carbonate that reacts with the acid in the acid rain and leads to the formation of a hard substance called gypsum. After the formation of gypsym, the stones of monuments gets severely affected and get displaced from their position.

$\huge\bf{Extra\: Information :}$

• Acid rain are the droplets of water vapours that gets mixed with the harmful substances and chemical compounds having low pH that are suspended in the atmosphere.
• These chemical compounds includes several harmful acids such as Nitric acid or sulphuric acid.
• The acid rain is acidic in the nature. A rain free of chemical substances have a pH that ranges between 5.0 and 5.5, but on the other hand, acid rain have the pH of about 4.0.
