How long does it take for copper to oxidize and turn green after being exposed to water Do you have any reference materials?
The time it takes for copper to oxidize and turn green after being exposed to water can vary depending on environmental factors such as humidity and temperature. Generally, this process, known as patina formation, can take anywhere from a few weeks to several months. If you are looking for specific reference materials on this topic, I recommend consulting scientific journals or textbooks on corrosion and material science.
What else can I help you with?
Does copper oxidize when exposed to water?
Yes, copper can oxidize when exposed to water, forming a greenish layer called copper oxide.
How can I oxidize copper to achieve a green patina?
To oxidize copper and achieve a green patina, you can expose the copper to a combination of oxygen, moisture, and acidic substances like vinegar or saltwater. This process will create a chemical reaction that forms the green patina on the copper surface.
How can I oxidize copper at home?
To oxidize copper at home, you can create a solution of vinegar and salt and soak the copper item in it. Another method is to use a mixture of ammonia and salt to achieve oxidation on the copper surface. Remember to wear gloves and work in a well-ventilated area when handling these chemicals.
Why do coins oxidize?
Coins oxidize when exposed to oxygen in the air, leading to the formation of a layer of oxidation on their surface. This oxidation is typically seen as a greenish color, known as patina, which is caused by the reaction of the metal in the coin with oxygen and moisture in the air. The presence of copper in many coins makes them particularly prone to oxidation.
What metal goes black in the air?
copper,and some precious metals, when exposed to air, turn black, like silver(completely turns black when exposed to air),gold(black spots appear),and others,maybe platinum.
Does copper oxidize when exposed to water?
Yes, copper can oxidize when exposed to water, forming a greenish layer called copper oxide.
What are advantages and disadvantages of copper-coated stainless steel water piping?
I cannot imagine any advantage of copper coating stainless? Stainless will not oxidize as readily as copper. I have uses lead coated copper flashing that was exposed to acid rain and bird droppings etc.
What two elements oxidize as they combine?
copper and oxygen
How can I oxidize copper to achieve a green patina?
To oxidize copper and achieve a green patina, you can expose the copper to a combination of oxygen, moisture, and acidic substances like vinegar or saltwater. This process will create a chemical reaction that forms the green patina on the copper surface.
How does copper conduct electricity differently when exposed to lightning compared to other materials?
When copper is exposed to lightning, it conducts electricity better than other materials because it has a high electrical conductivity. This means that copper allows electricity to flow through it more easily, making it a preferred material for conducting electricity during lightning strikes.
How to make copper white?
Copper can turn greenish-White if left /encouraged to oxidize. Otherwise you have to paint it.
How can I oxidize copper at home?
To oxidize copper at home, you can create a solution of vinegar and salt and soak the copper item in it. Another method is to use a mixture of ammonia and salt to achieve oxidation on the copper surface. Remember to wear gloves and work in a well-ventilated area when handling these chemicals.
What happens to copper metal when it sits in H2O?
It will oxidize, which causes it to turn green.
Why do coins oxidize?

What makes pennies rust?
Pennies don't rust. Rust technically speaking is iron oxide and pennies have little to no iron. They do however oxidize, tuning them green from the copper which makes up most of the metal they are made from.
Which metal get green coating whrn exposed to air?
Copper... the surface of the copper that's exposed to the air reacts with oxygen to create copper oxide.
What metal goes black in the air?
copper,and some precious metals, when exposed to air, turn black, like silver(completely turns black when exposed to air),gold(black spots appear),and others,maybe platinum.
