Why does a copper vessel turn green in color in the rainy season?
An unprotected copper vessel will turn green eventually due to several chemical reactions, regardless of the environment. The wetness of the rainy season simply speeds up the chemical process. The process by which copper turns green in color is due to the slow oxidation of the copper metal into its oxides. Initially copper oxide forms (reddish), replaced by cuprous and cupric sulfide (color varies), and finally by copper carbonate (greenish). The final copper carbonate is highly resistant to corrosion and hence the vessel will remain green.
Does copper and steam react?
No copper kettles are coated with special chemicals which prevents steam reacting with it just like aluminum forms an oxide layer which prevents it from further reacting. If no layer were put on the kettle it would turn greenish because copper would have reacted................. Hope I was useful ;-) Kyle.
What will happen if copper metal is added to iron sulfate solution?
nothing will happen as i have done this experiment. I think it is because iron is more reactive than copper, so the copper can't take away the sulphate. but if you added the iron to a copper sulphate solution the product would be iron sulphate this reaction is called displacment.

Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
When iron oxide is made does the iron take the oxygen out of the water or out of the air?
It takes the oxygen from air because without the presence of air, iron cannot turn into ferric oxide. The iron first reacts with air and then reacts with water to form rust.
Why does a penny turn green in water?
The copper reacts with the oxygen in water to form copper oxide and hydrogen ions. This is copper oxide is a green compound.
Why does copper tarnish and turn green?
copper tarnish and turn green because of present of iron in it.
Why does copper turn red to green?
Cause of the oxide cotende in it
What solid residue will turn from green to black if heated?
Iron(II) carbonate [green] to Iron(II) oxide.
Why does copper turn black when it meets oxygen?
Foolish Fools!, it does infact turn Green! because the oxygen bonds with the copper to form copper oxide, wich is green, it reflects different fractions of light to the copper
When copper turns green when exposed to the environment a physical or chemical change?
First, copper doesn't "turn green," it reacts with oxygen in the air to form copper oxide. This is a chemical change, because copper oxide is a substance that was not there before.
Why does carrot water turn green after a time?
Iron oxide or something, init.
Does 100g of iron turn into 100g of iron oxide?
100g of iron will not turn into 100g of iron oxide because the iron oxide will have gained mass due to the oxygen that will have combined with the iron.
What causes iron to rust and lady liberty turn green?
The statue of liberty is made from copper, not iron. By reactions with carbon dioxide and water green hydrated copper carbonate is formed.
What will happen if hydrogen gas is heated over copper oxide?
the copper oxide will turn red
Why copper articles becomes green on exposure to moist air?
they turn green due to oxidation. in iron it is red and called rust, in copper it is called patina
What happens when iron nail are placed in copper sulphate solutions with word equation?
If iron nails are placed in a copper sulphate solution they turn green and rusted which means they become copper plated nails.I think the word equation is :iron + copper sulphate - copper + Iron sulphate.Iron displaces copper
