Copper turns a greenish color is it chemical or physical change?
The color change of copper to green is a chemical change. This is due to the formation of a green patina on the surface of the copper, typically caused by oxidation reactions with the air and moisture.
Will the color change if copper metal is added to silver nitrate solution change?
Yes, a color change will occur. When copper metal is added to silver nitrate solution, a displacement reaction takes place where copper replaces silver in the solution. This leads to the formation of copper nitrate and silver metal, resulting in a change in color from clear to blue as silver particles are formed.
Why does copper chloride change colour when heated?
Copper chloride changes color when heated due to a thermally-induced chemical reaction that leads to the formation of different copper compounds. This color change is attributed to the shifting of electrons within the copper ions, resulting in the absorption and reflection of light at different wavelengths, giving rise to a distinct color appearance.
Why does copper sulfate burn blue?
Copper sulfate burns blue because of the presence of copper ions emitting a characteristic blue color when heated. This color is a result of the electronic transitions that occur within the copper ions as they absorb and emit energy in the form of light.
Can you anodize copper to change its color and improve its durability?
Yes, copper can be anodized to change its color and improve its durability. Anodizing is an electrochemical process that creates a protective oxide layer on the surface of the copper, which can be dyed to achieve different colors and enhance its resistance to corrosion and wear.
Why does copper change color to a greenish color?
Copper changes color to green either because of the weather or a physical change

What cause the staute of liberty to change to a greennish color?
The color comes from the oxidation of copper.
Is copper turing green a physical or chemical change?
It's a chemical change. Copper oxidizes to form copper oxide, which is similar to iron rusting. A color change very often indicates a chemical change.
Did the color of Copper ( ) sulfate change?
We can not answer this as we were not there to observe the experiment. Only YOU can answer this!
What is observed when air is passed over heated copper powder?
When air is passed over heated copper powder, the copper powder will react with the oxygen in the air, leading to the formation of copper oxide. This reaction can result in a color change in the copper powder from its original metallic color to a reddish-brown color.
Why does copper chloride change colour when heated?
Copper chloride changes color when heated due to a thermally-induced chemical reaction that leads to the formation of different copper compounds. This color change is attributed to the shifting of electrons within the copper ions, resulting in the absorption and reflection of light at different wavelengths, giving rise to a distinct color appearance.

Why does the color of copper sulfate solution changes during electrolysis?
The color change in copper sulfate solution during electrolysis occurs because copper ions from the solution are attracted to the cathode, where they are reduced to form solid copper metal. This causes the solution to turn from blue to clear as the copper ions are removed.
How does the statue of liberty's change relate to science?
There is a thin copper sheeting over the iron frame of the statue. The copper changes color due to the sea air from a copper color to a green. That is a chemical reaction when the salt in the sea air reacts to the copper.
