What are the colors of silver metal and copper nitrate in water?
The colour of silver metal in water is whiteThe colour of copper nitrate in water is blue (due to the Cu++ ion).
Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
What flame colour does copper chloride give?
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
What colour is copper sulfate?
blue
Is copper sulfate a blue solid?
Hydrated copper sulphate (CuSO4.5H2O) is blue in colour. Anhydrous copper sulphate (CuSO4) is white in colour.
What is the colour of copper metal?
the color of Cu 2 atom is blueans2. Copper metal is an orange-brown colour. Many copper salts are green or blue.We cannot meaningfully talk of the colour of a copper atom.
What is the colour of the crystales of copper sulphate?

What color does copper become when it reacts with acetic acid?
Copper can turn greenish-blue when it reacts with acetic acid due to the formation of copper(II) acetate, which is a blue-green compound. This color change is a result of the oxidation of copper metal to copper ions in the presence of acetic acid.
Why does the water colour change to blue when copper sulphate was added?
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
What is the colour of copper chloride solution?
Copper chloride solution typically appears blue or green in color.
Why does iron filings in copper sulphate solution become colourless from green after sometime?
Copper sulfate solution starts of a blue colour. When Iron metal is added to the solution a REDOX reaction begins in which the copper is reduced (gains electrons) to become copper metal and the iron is oxidised (loses electrons) to become iron ions. When the iron ions go into solution, it will change to a green colour which is the colour of iron (II) sulfate. As a general principle, a more reactive metal will displace a less reactive metal from solution by the process described above.
What colour does blue copper chloride turn when moistened?
A darker shade of blue.
