Question

What are the affects of acid rain on Bridges? Exaplin briefly if you want brainlist.

Answer 1

here your answer


Yes, acid rain does in fact harm building materials. Calcium carbonate that is commonly found in building materials dissolves in weak acids. Even though many metals corrode, stone and paint deteriorate, which lowers the value of the architecture that is built with these building materials.Acid rain most diffidently affects architecture. A great example is The Statue of Liberty, which was once copper, because of acid rain it is now green. Much architecture today involves the use of marble and limestone. These two contain calcium carbonate, which dissolves in weak acids, like we discussed in the first paragraph.  Acid rain also does affect roads, highways, and bridges as well. It causes them to corrode and become weaker. This is a big safety hazard. Bridges could even collapse on themselves if they become too weak. Highways and roads will also become dangerous to travel on.

Answer 2

HELLO THERE!

Acid rain: Some acidic gases (called as acid anhydrides) react with water to form their respective acids. For example, carbon dioxide forms carbonic acid, sulphur dioxide forms sulphuric acid, nitrogen dioxide forms nitric acid, etc.

Now, we know that carbon dioxide is present in the atmosphere naturally, so when it rains, it is not surprising that some of the carbon dioxide gas dissolves in the rain water to form carbonic acid, which falls on earth. Carbonic acid is not so strong an acid. However, nitric acid and sulphuric acids are strong mineral acids.

Due to vehicle emission and emission from different factories, a huge amount of sulphur dioxide and nitrogen dioxide gases are left into the atmosphere, which leads to the rise of droplets of nitric acid and sulphuric acid with rain water.

This acid rain has many harmful effects on Earth. Your question asks for the effect it has on Bridges:

Bridges are made up of concrete, and maybe supported by iron or other strong metals. The acids are so strong that when they fall on these metals, they corrode them by reacting (as on reaction, other products are formed which are not as strong as the metal was, hence the bridge weakens).

Long-term exposure of a bridge to acid rain may cause the bridge to completely corrode and batter. The bridge hence keeps on weakening and  losing its power to withstand the weight of cars.

Ultimately it breaks, leading to a huge loss of money and human effort, and it may end up taking lives.

Acid rain also have bad impact on roads, buildings and lives of plants and animals.
