How do you make copper oxide from copper carbonate?

Answer 1

Carbonate Decomposition

Aim: To investigate the decomposition of a carbonate.

Equipment:

· Copper Carbonate (CuCO3)

· Limewater

· Bunsen Burner

· Matches

· Test tubes

· Clamp and stand

· Hydrochloric Acid

· Electronic Scales

Method:

1. Weighed Copper Carbonate by taring empty test tube.

2. Placed some Copper Carbonate in a test tube fitted with gas delivery tube

and stopper.

3. Clamped the test tube to the stand at a slight angle.

4. Half filled another test tube with limewater and placed the other end of gas

delivery tube into it.

5. Using a small blue flame gently heated the carbonate. Observed what

happened.

6. Removed gas tube from limewater before turning off the Bunsen burner.

7. Allowed to cool

8. Weighed the remaining Copper Carbonate.

9. Added approximately 5ml of Hydrochloric Acid to the solid residue (Copper

Oxide) from the decomposition reaction.

10. Transferred a small amount of original Copper Carbonate to new test tube

and added same amount of Hydrochloric Acid to that. Recorded observations.

Results: Observations from Decomposition: The limewater turned milky.

Observations from HCl & Copper Oxide: Small bubbles. Hardly a reaction.

Observations from HCl & Copper Carbonate: Bubbles & fizzing. Small amount

of heat generated. Turned milky green in colour. Reacted immeadiately.

Conclusion: The limewater proved that Carbon Dioxide was produced as a result of thedecomposition reaction.

The Copper Oxide test showed that theoretically there should be no reaction with HCl. Copper Carbonate, however, theoretically, should react.

Evaluation: Overall, the experiment was a success except for the fact that the HCl shouldn'thave reacted with the Copper Oxide but did. This is probably due to the fact there

was some Copper Carbonate still stuck to the side of the test tube and the HCl

reacted with that.

Answer 2

The process of extracting copper of copper carbonate

The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces.

• The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

• The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed.

• Most of the sulphur in the chalcopyrite turns into sulphur dioxide gas. This is used to make sulphuric acid via the Contact Process.

An overall equation for this series of steps is:

The copper(I) sulphide produced is converted to copper with a final blast of air.

Answer 3

Strongly heating Copper carbonate makes it decompose into black Copper(II) oxide (CuO) and Carbon dioxide. When this black powder is reacted with reducing agents like hydrogen or Carbon monoxide it is reduced to elementary copper.

CuO + H2 ----> Cu + H2O

CuO + CO ----> Cu + CO2

It can also be reacted with concentrated Phenol to yield copper.

C6H5OH + CuO ----> CO2 + H2O + Cu

Answer 4

You don't. Copper ore CONTAINS copper oxide.

Answer 5

Copper sulfate(sulphate) can be made by adding Copper Oxide to a beaker full of sulfuric acid. Water is also created as well.

Answer 6

Copper can be found by mining it from various countries. It is a natural mineral so it does not need to be made.

Answer 7

You heat the copper carbonate to create copper oxide but I'm not sure what temperature you have to heat it to.
