When copper react with sodium hydroxide, copper hydroxide is one of the products which has a distinct colour, so...
1) Add a few drops of dilute sodium hydroxide to the solution you wish to test for copper ions
2) If a blue precipitate forms (copper hydroxide is insoluble in water), then it's likely that copper ions are present
3) To confirm the presence of copper ions, add ammonia solution & if the precipitate dissolves, forming a deep blue solution, you know copper ions are present
Most chemists currently measure copper levels in zinc oxide..
First you need to determine the concentration of copper in this water. Then report it to the volume of the sample.
how can you tell if something is cooper
In a flame test the copper ions in copper chloride will produce a 'blue/green' flame. To test for metal ions, the flame colour in a flame test is indicative of the metal present. Lithium = Red Sodium = Yellow Potassium = Lilac (pale purple). There are many more flame test colours.
A Flame Test. Using a platinum or nichrome wire. Clean the wire in hydrochloric acid, Then dip the wire into a solution containing copper(II) ions. e.g. copper sulphate solution. The pass the wire through a Bunsen burner flame. The flame should burn a green/blue colour.
It depends on the compound. If the compound contains copper (I) ions, the flame is blue. If the compound contains copper (II) ions bonded to a halogen (F, Cl, I, Br, or At), the flame will be a blue-green color, and if the compound contains copper (II) ions and no halogens, the flame will be a deep green.Copper sulfate burns a light/sky blue colour.
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
These Copper(II) ions are reduced to insoluble Copper(I) ions, while the reaction.
The colour of any sample containing copper ions burns with a bluish green flame in the flame test.
Copper carbide is a salt. As the element implies, the ions present are copper ions and carbide ions. Carbide ions are made of carbon atoms.
There are three copper II ions (Cu2+) and two phosphate ions (PO43-).

Copper (II) Nitrate burns in a Green flame
It depends on the compound. If the compound contains copper (I) ions, the flame is blue. If the compound contains copper (II) ions bonded to a halogen (F, Cl, I, Br, or At), the flame will be a blue-green color, and if the compound contains copper (II) ions and no halogens, the flame will be a deep green.Copper sulfate burns a light/sky blue colour.
Copper ions can have a +1 or +2 charge. They are represented by the following: Copper(I) ions are represented by the symbol Ca+ and Copper(II) are represented by the symbol Ca2+.
Copper and carbonate ions form copper carbonate. In practice, copper carbonate usually contains hydroxide ions as well.
Copper atoms will dissolve into the water, giving off electrons at the anode. At the cathode, the copper ions will be deposited on the electrode and acquire electrons.
These Copper(II) ions are reduced to insoluble Copper(I) ions, while the reaction.

Copper atoms lose one or two electrons when forming an ionic bond with oxygen. The oxygen atoms gain the electrons released from the copper atoms when forming an ionic bond with copper. The electrostatic attraction between the positive and negative ions forms the ionic bond. Copper can form two different ions, copper(I) and copper(II). Copper(I) ions have a charge of 1+ (Cu+) and copper(II) ions have a charge of 2+ (Cu2+). Oxide ions have a charge of 2+ (O2-). Copper(I) oxide has a formula unit of Cu2O. Copper(II) oxide has a formula unit of CuO.
