Which type of weathering is responsible for the green patina that forms on the copper skin of the Statue of Liberty

Question

Is it hydrillas dissolution carbonization or oxidization

Answer 1

The green patina that forms on the copper skin of the Statue of Liberty is primarily due to oxidation. When copper is exposed to the elements, it reacts with oxygen in the air and moisture, leading to the formation of copper oxide and other compounds, such as copper carbonate and copper sulfate. This process results in the characteristic green color known as verdigris. While hydration and other chemical processes can contribute to the patina, oxidation is the primary weathering process responsible for its formation.
