What makes copper go green?
The green material on copper is oxidation. On iron or steel it is called rust, on copper and bronze is it called a patina. Unlike the rust on steel and iron that damages the metal, rust on copper, bronze, and even aluminum can protect the under-laying metal. You can even make the green different shades by applying different oxidizers, which some artists use in place of painting the metal.
Why does wearing a copper bracelet turn your skin green?
The green color on your skin after wearing a copper bracelet is a result of a chemical reaction between the copper and your skin's acids and oils, producing copper salts which oxidize and leave a green residue on your skin. This reaction is harmless and can easily be washed off with soap and water.
What color goes with copper color?
Colors that go well with copper include navy blue, deep emerald green, and shades of cream or ivory. These colors create a rich and sophisticated look when paired with copper accents.

How do you make copper powder?
I dry it with acetone right on the vacuum filter after its been washed. This removes the water and the acetone can be then removed by gentle warming. But depending on your particle sizes you may need the inert atmosphere for it (Nitrogen, Argon) as the fine one can be pyrophoric in air.
What makes copper go green and how long does it take to change color?
Copper turns green due to a process called oxidation, forming copper oxide and copper carbonate on its surface. This greenish patina is known as verdigris and can take several years to develop, depending on the environment and exposure to elements like moisture and air.
Why does copper carbonate decompose to make copper 2 oxide not copper 1 oxide?
Because it is easier. The molecular formula of copper carbonate is CuCO3. When it decomposes it loses a CO2 molecule. If it became Copper 1 oxide(Cu2O then it would have to combine with another molecule(releasing O). Instead it becames copper2 oxide(CuO) because that is an easier transition.

Why does copper and silver bangles turn green and black respectivly after their worn for many days?
They Tarnish (this is like rusting in iron, but slower). The moisure in your sweat, the warmth in your skin and the oxygen in the air all start to react with the metals. With silver, this makes silver oxide and hydroxide. This is a very slow process and silver tarnishing is very slow. With copper, this moke black copper oxide and green copper hydroxide (comman name verdigris, means green/grey). This process is also slow, but faster than silver. You can see evidence of this on old bronze statues and copper domes, which go green with weather and time.
What happens when a piece copper wire is heated in the outer region of the flame until its red hot?
When a copper wire is heated in the outer region of a flame until it's red hot, it undergoes oxidation which forms a layer of copper oxide on its surface. This layer appears as a black residue and can be easily removed through polishing to reveal the original copper surface beneath.

Do black wires always go to brass color screws?
In residential 120 volt wall outlet wiring yes the black always goes to the brass/copper screw. White is connected to the silver screw, and ground to the green screw.
Why do statues go green?
The reason that some statues go green is because they contain copper, and when copper reacts water in covers in a coating that protects it. The same happens when Iron reaches water, but this coating is known as rust. This is called Tarnishing.
What colors go with blue red and black?
green
