Copper burns with a green flame when ignited with oxygen.
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
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.
It usually produces a green sort of colour unless you hold the experiment out incorrectly
The flame produced by burning acetylene gas is typically colorless when burned in pure oxygen. However, if burned in air, it can produce a slight yellowish flame due to incomplete combustion, which may also contain some soot.
Copper chloride typically produces a blue-green flame when burned due to the presence of copper ions in the compound. The green color is a characteristic emission caused by the excitation of electrons in the copper atoms.

Copper wire would not be suitable for use in fame tests due to the fact it would cause the flame to change colour (usually to green). The experimenter wants to observe the colour change produced by the sample, not the wire.

The flame color of barium burning in oxygen is green.
Copper II nitrate typically produces a blue-green flame when burned.
Copper gives off a green flame when burned. So, green.
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
it is like the color but gold more
