the color of Cu 2 atom is blue
ans2. 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.
The colour of silver metal in water is whiteThe colour of copper nitrate in water is blue (due to the Cu++ ion).
When copper oxide is added to hydrogen, a redox reaction occurs. The color change observed is from black copper oxide to reddish-brown copper metal, indicating the reduction of copper oxide to copper metal by hydrogen gas.
Metal is a category of elements but copper chloride is not an element. It is a compound made from chlorine and copper. Among these copper is a metal and chlorine is a non-metal.
Copper sulfate is a salt compound made of copper, sulfur, and oxygen. Copper is a metal, whereas sulfur is a non-metal. So, copper sulfate contains both metal and non-metal elements.
Copper sulfate is not a metal There are two compounds called Copper Sulfate, which are salts of the metal Copper. CuSO4 is Copper (II) Sulfate, once known as Cupric Sulfate. Cu2SO4 is Copper (I) Sulfate, once known as Cuprous Sulfate.
The metal that will destroy the blue colour of Copper ions is any metal above copper in the reactivity series, such as calcium.
COPPER often has a reddish-orangey colour.
The colour of silver metal in water is whiteThe colour of copper nitrate in water is blue (due to the Cu++ ion).
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.
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
copper is a metal
Copper metal will turn a silver color when placed in silver nitrate solution due to a displacement reaction where silver ions (Ag+) from the solution form solid silver metal on the surface of the copper.
When copper oxide is added to hydrogen, a redox reaction occurs. The color change observed is from black copper oxide to reddish-brown copper metal, indicating the reduction of copper oxide to copper metal by hydrogen gas.
Copper is a metal. It is also considered as a mineral as well. You can find traces of copper in your blood.
It depends on the metal in the green sulphate solution.
The metal powder that turns black when heated in an open dish is likely to be magnesium. This is due to the formation of magnesium oxide on the surface of the metal powder when it reacts with oxygen in the air during heating.
when copper is put with water it turns green like the statue of liberty it is actually a browny bronze colour but when water and other chemicals react with it, it chages colour to a green colour
