Does copper also get rusted ? Explain.
Answers
Answer:
Rusting is commonly referred to as oxidation and takes place when iron or metal alloys containing iron (i.e. steel) are exposed to water and oxygen for extended periods. ... Other metals such as bronze and copper also undergo oxidation, leading to corrosion. So, the answer to the question is NO, copper does not rust.
Explanation:
Rust, commonly referred to as oxidation, occurs when iron or metal alloys that contain iron, such as steel, are exposed to oxygen and water for a long period of time.
Rust forms when iron undergoes the process of oxidation but not all oxidation forms rust. As stated previously, only iron or alloys that contain iron can rust, but other metals can corrode in a similar way.
Corrosion occurs when an element that easily loses its electrons (like some metals) combines with an element that absorbs extra electrons (oxygen) and then comes into contact with an electrolyte solution (water). The job of the water in the corrosion process is to accelerate the flow of electrons from the metal to the oxygen.
This process is called a redox reaction and is actually two chemical processes that happen at the same time: reduction and oxidation.
Reduction is the name of the chemical reaction that occurs when a molecule gains an electron. This is oxygen’s role in metal corrosion.
Oxidation is the opposite of reduction and is the name of the chemical reaction that occurs when a molecule loses an electron. This is the metal’s role in metal corrosion. Rust and the patina (weird green color) of copper are the visible results of the metals losing their electrons to the air.
Copper does not rust, however, it does corrode. Copper is naturally brown and turns a shade of bright green as it corrodes. While some consider copper’s reaction to be tarnish rather than oxidation, the metal still undergoes a similar “rusting” process.
In a natural environment, copper is extremely reluctant to corrode. The type of corrosion that ultimately breaks copper drinking pipes is called erosion corrosion and it only occurs due to exposure to flowing, turbulent water over a long period of time.
