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.
the acid rain
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.
erosion corrosion, close?
acid rain (it can destroy limestone) (it also made the Statue of Liberty green)
Acids can destroy many objects by corrosion.
Phosphoric acid can decrease the corrosion resistance of stainless steel by promoting the formation of localized corrosion, such as pitting and crevice corrosion. This is due to the acid's ability to break down the protective passive film on the stainless steel surface, making it more susceptible to corrosion.
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.
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.
The rate at which acid rain reacts with a statue is influenced by factors such as the composition of the statue (e.g. limestone is more susceptible), the concentration of acid in the rain, the duration of exposure, and the weather conditions (e.g. temperature and humidity). Additionally, the presence of protective coatings or treatments on the statue can also affect the reaction rate.
Acid corrosion can weaken metal structures by breaking down the material, leading to structural damage and reduced longevity. This can compromise the performance and safety of the structure over time.
By altering (eating into) the minerals form which the stone is made.
Citric acid can act as a chelating agent, forming complexes with metal ions. This can result in the dissolution of the metal surface, leading to corrosion or rusting. The rate of corrosion depends on factors such as concentration of citric acid, pH, and temperature.
