It depends on the compound. If the compound contains copper (I) ions, the flame is blue. If the compound contains copper (II) ions bonded to a halogen (F, Cl, I, Br, or At), the flame will be a blue-green color, and if the compound contains copper (II) ions and no halogens, the flame will be a deep green.
Copper sulfate burns a light/sky blue colour.

What colour does copper nitrate compound when you burn it?
Copper nitrate does not have a distinctive color when burned. The flame may likely be blue or green due to the presence of copper ions.
What color does the copper burn in flame test?
When copper is heated in a flame, it burns with a blue-green flame. The color is due to the emission of energy in the form of light as electrons in the copper atoms are excited and then return to their ground state.
When copper chloride reacts with aluminum why does the color of the solution seem to fade?
When copper chloride reacts with aluminum, the aluminum replaces the copper in the compound through a single displacement reaction. The resulting compound formed, aluminum chloride, is colorless in solution. Therefore, the color of the solution appears to fade as the copper is displaced and the products of the reaction are colorless.
What copper compound is purple?
No one copper compound is purple, the Cuprous oxide Cu2O is red and ammonical copper sulphate is blue the combination of these compounds may produce purple colour.
What happens when you heat copper with sulfur?
The product is Copper Sulphate. Formula = CuSO4
What colour does copper nitrate compound when you burn it?
Copper nitrate does not have a distinctive color when burned. The flame may likely be blue or green due to the presence of copper ions.
What colour flame do you get when you burn copper chloride?
Burning copper chloride produces a green flame due to the presence of copper ions in the compound. The green color is a result of specific energy transitions within the copper ions when they are heated.
Why does cupric chloride burn blue?
The color is due to the radiation emitted by copper.
Is copper sulfur a compound?
There is no compound as copper sulfur, but copper sulfate is a compound, yes.
What color is the flame when you burn copper II chloride?
A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.

Test for presence of water in anhydrous copper sulphate?
To test for the presence of water in anhydrous copper sulfate, heat a small sample of the compound in a test tube. If the compound changes color from white to blue, it indicates that water is present in the compound. This color change happens as the anhydrous copper sulfate absorbs water vapor from the air, converting back into hydrated copper sulfate.
What happens when you heat copper with sulfur?
The product is Copper Sulphate. Formula = CuSO4
Why does white copper sulphate turn blue when water is added?
White copper sulfate is anhydrous, meaning it does not contain water molecules. When water is added to white copper sulfate, it forms a hydrate compound called blue copper sulfate pentahydrate. The water molecules coordinate with the copper ions, causing the compound to change color from white to blue.
What colour is copper oxide and why?
Copper oxide is typically black or dark brown in color. This coloration is due to the presence of oxygen, which causes copper to oxidize and form the copper oxide compound. The specific shade may vary depending on the specific oxidation state of the copper ions in the compound.
