A.o.A it is the demand of flame test that salt should be easily vapourised as metalic chloride for this purpose we wet the given salt with acid (HCl) so that it change into chloride but copper cannot remove hydrogen(As Au,Ag,Pt) from acid so cannot changed into chloride and not used in flame test.
but if there is chloride salt of copper it can be easily used for flame test with-out use of acid.....
Copper sulfate is not typically used in flame tests because it does not produce a characteristic flame color that is easily distinguishable from other compounds. Other metal salts, such as sodium, potassium, and strontium, are commonly used in flame tests because they produce distinct and easily recognizable flame colors that help identify specific elements.

Can we use copper wire in the flame test?
No, copper wire would not produce a distinctive color in a flame test. The flame test is typically used for metals that produce easily identifiable colors when burned in a flame, such as lithium (red), sodium (yellow), or potassium (purple). Copper does not exhibit this characteristic.
What element is responsible for the green flame produced in the beilstein test?
Copper is responsible for the green flame observed in the Beilstein test, which is a qualitative test used to detect the presence of halogens, especially chlorine, in organic compounds. When a compound containing chlorine is heated with copper oxide, the chlorine is converted to a volatile copper(I) chloride compound, which produces a green flame when heated.
What metal burns with a blue flame?
In qualitative analysis, flame tests are used in confirming what kind of metal is present in a solution. The green flame or bluish-green flame color is usually present whenever copper metal is present in a solution.
What happen if you add the copper sulphate to sodium hydroxide?
If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.
Test metal for copper?
One common way to test if a metal contains copper is to perform a flame test. Copper typically gives a green flame when heated. Another method is to use a chemical reagent such as potassium ferrocyanide, which gives a brown color in the presence of copper ions. Additionally, an acid like nitric acid can be used to test for the characteristic blue color of copper ions in solution.

What are uses of copper sulphate?
used as a herbicide, fungicide and pesticide. Also to test blood for anaemia and usually at schools used to make crystals

Which part of the flame is used to perform the flame test?
All but the very center bottom. The general color will change ie, green for Copper.
Why copper rods not used to separate zinc from zinc sulphate?
Copper rods cannot separate zinc from zinc sulphate because copper is less reactive than zinc, and cannot separate the zinc which is more reactive than copper. If you get copper sulphate and add some zinc to it, you will see solid copper appearing on the bottom of the test tube... The copper cannot push out the zinc from the solution and take its place.
Can copper sulphate used on cuts?
Copper sulphate obtained from the pharmacy can be used on cuts. Other sources of copper sulfate, such as root removing compounds cannot be used on the skin because they contain other substances. Copper sulphate can help to kill pathogens that cause infection.
What substance is used as a control in a Biuret test?
Sodium hydroxide is used as a control in a Biuret test to ensure that the alkaline pH conditions are optimal for the reaction to occur.
Which metal used to recover copper from a solution of copper sulphate?
Fe
