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).
Solution contains metallic ion blue in colour flame test produce blue green colour The solution forms a precipitate when sodium hydroxide is added to the solution What is the ion in the solution?
The metallic ion in the solution is likely copper(II) ion (Cu^2+). This is based on its blue color in a flame test, which gives a blue-green flame, and the formation of a blue precipitate when sodium hydroxide is added, indicating the presence of Cu(OH)2.
What are two different charges copper can have?
Copper can have a +1 charge, known as cuprous ion, and a +2 charge, known as cupric ion. These charges depend on the oxidation state of copper in a compound.
What is the oxidation state of cupric ion in copper tartar-ate?
The oxidation state of the cupric ion in copper tartarate is +2. Copper (II) ion, or cupric ion, has an oxidation state of +2 due to the loss of 2 electrons. In the case of copper tartarate, the ligand (tartarate) does not affect the oxidation state of the central copper ion.
What is the charge on the copper ion in the compound CuF2?
The charge on the copper ion in CuF2 is +2. This is because fluorine typically has a charge of -1, and there are two fluorine atoms in the compound which balances out the charge of the copper ion.
What flame colour does copper chloride give?
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
What ion is responsible for the blue colour?
The ion responsible for the blue color in many compounds is usually copper(II) ion (Cu2+). Copper(II) compounds often appear blue due to the absorption of certain wavelengths of light in the visible spectrum associated with the ion's electronic structure.
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 are the colors of silver metal and copper nitrate in water?

What compound will be formed between copper ion and carbonate ion?
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
What is the metallic ion in copper II chloride?
The metallic ion in copper II chloride is copper (Cu2+).
What portion of the compound copper sulfateCuSO4 is covalently bonded polyatomic ion?
In copper sulfate (CuSO4), the polyatomic ion is SO4^2-, which is covalently bonded. The copper ion (Cu) is not part of the polyatomic ion and is ionically bonded to the sulfate ion.
What are two different charges copper can have?
Copper can have a +1 charge, known as cuprous ion, and a +2 charge, known as cupric ion. These charges depend on the oxidation state of copper in a compound.
When copper combines with oxygen to form copper (II) oxide the charge of the copper ion is?
When copper combines with oxygen to form copper (II) oxide, the charge of the copper ion is +2. This is because in copper (II) oxide, each copper ion has lost two electrons to oxygen atoms, resulting in a +2 charge.
What is the oxidation state of cupric ion in copper tartar-ate?
The oxidation state of the cupric ion in copper tartarate is +2. Copper (II) ion, or cupric ion, has an oxidation state of +2 due to the loss of 2 electrons. In the case of copper tartarate, the ligand (tartarate) does not affect the oxidation state of the central copper ion.
What is the charge on the copper ion in Cu3P?
The charge on the copper ion in Cu3P is +1. This is because the overall charge for the compound Cu3P is 0, and since there are three copper ions present, each copper ion must have a charge of +1 to balance the -3 charge of the phosphorus ion.
