How does acid rain affect the corrosion of the Statue of Liberty?

∙ 15y ago
Statue of libery is made from copper (Cu). Copper reacts when acid rain (2H+ + SO42-) falls forming copper sulfide (CuS, but other types of sulfides also possible). CuS oxidises slowly to copper sulfate (CuSO4) which has green colour. So, the statue of liberty has changed its colour from black (or copperish) to green.

∙ 11y agoWhen sulphur pollutants fall on to buildings made from limestone and sandstone they react with minerals in the stone to form a powdery substance that can be washed away by rain. Famous buildings like the Statue of Liberty in New York, the Taj Mahal in India and St. Paul's Cathedral in London have all been damaged by this sort of air pollution.
Acid rain can also damage stained glass windows in churches, railway lines and steel bridges. The acid rain slowly eats away them all. Building materials crumble away, metals are corroded, the colour of paint is spoiled, leather is weakened and crusts form on the surface of glass.
If people start reducing emissions we could save all these buildings.

What is the long term impact of water and oxygen on copper?
Corrosion or the coper item resulting in holes or structurally weakened copper. It turns very green; like the statue of liberty which is also made of copper. It should be cleaned with acid to remove corrosion.
How does air pollution effect the statue of liberty?
the acid rain
What kind of affect does acid rain have on monuments?
erosion corrosion, close?
How does acid affect an objects property?
Acids can destroy many objects by corrosion.
Rain that contains a large amount of acid?
acid rain (it can destroy limestone) (it also made the Statue of Liberty green)
What metal turns green and why?
Copper turns green after a while because of weathering and corrosion. It is in general the Oxygen in our atmosphere that bonds with the copper, forming a protective layer of "green" oxydation or corrosion. Further information: Many buildings have copper-roofs. It is a metal that is easy to cut and form. It is also highly corrosion resistant because the corrosion formed also protects it from further corrosion. Acid rain however is able to wash away part of the corrosion formed. This mean that in highly polluted areas, Copper is not such a good choice. The Statue of Liberty used to be the iconic copper color.
How is weathering affecting the Statue of Liberty?
Weathering has affected the Statue of Liberty because the statue was once a coper color. Acid rain soon caused it to become a green color. Wind, water, snow, and the sun (forms of weathering) also caused the statue's natural color to wash away.
Is the Statue of Liberty a physical change or a chemical change?
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
How can acid rain affect a statue that was made of stone?
By altering (eating into) the minerals form which the stone is made.
How would acid rain effect a skyscraper bub?
Acid rain can affect skyscrapers by degrading the steel and concrete they are made from. Builders combat this by using specialized materials that resist corrosion.
What causes the Statue of Liberty's color?
Originally, the Statue of Liberty was green, due to the fact that it is made of copper. However, after years of exposure to outdoor conditions, sulfuric acid in the rain has reacted with the copper, corroding the copper to produce copper salts. Copper can corrode into different colours depending on the conditions it is exposed to; in normal outdoor exposure, as is the case with the Statue of Liberty, copper usually corrodes into a blue-green colour.
Corrosion of tajmahal is due to?
acid rain....
