What are the decomposition steps for copper sulphate pentahydrated?
Wiki User
∙ 12y ago
Initial chemical formula is: CuSO4.5H2O.
Dehydration:
- CuSO4.3H2O at 63 0C
- CuSO4.H2O at 109 0C
- CuSO4 at 200 0C
Thermal decomposition after 650 0C:
CuSO4 = CuO + SO3

How do you make copper oxide from copper carbonate?
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.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
What is the chemical name of the product when copper reacts with gas in the air?
Copper reacts with the oxygen in the air in a process called oxidation. This occurs in several steps as seen in Kuba Jasinski’s answer. The reactions occur as the copper atoms give up some electrons (oxidation) to the oxygens (reduction) to create ionic compounds. This is a classic example of what is called a redox (reduction-oxidation) reaction.
What is the four steps that describe how copper ore is turned into useful products?
1. Copper ore is mined and crushed. 2. It must be processed to remove the useful mineral or element. 3. Smelting is the process used to obtain copper. In the smelting the ore is melted and material are removed. After smelting, the copper is refined ,or purified. 4. Then it is made into many types of products used in homes, businesses, and industry.
How can one sell scrap copper?
If you have any kind of scrap or damage cars, you can easily sell on Green Box Vehicle Recycling company, they deals all type of scrap and damage cars. Please visit their website (greenboxvehiclerecycling.co.uk)
Symbol equation when copper carbonate is heated?
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
What is copper chlorine?
Copper Chlorine is a cycle that is broken up into four steps. It is a thermochemical cycle for making hydrogen.
How can you change 'carbon' to 'copper' by changing one letter at a time?
In eight steps: CARBON -> CARTON -> CANTON -> CANTOR -> CANTER -> CARTER -> CARPER -> CAPPER -> COPPER.

How do you get copper metal from copper ore?
It depends upon nature of ore the most common ore of copper is Copper pyrite CuFeS2. the extraction of copper from this ore involves the following steps, 1-crushing, 2-grinding, 3-concentration of ore, 4-roastiong, 5-smelting, 6- preparation of blister copper and 7- electrorefining of blister copper.
What are the steps to prove that a burning of a candle is physical as well as a chemical change?
1. Melting of the candle is a physical change. 2. Burning and thermal decomposition are chemical changes.
What are the steps to do the biuret test?
1) Add 2cm3 of solution to be tested to a test-tube. 2) Add an equal volume of 5% potassium hydroxide* solution and mix. 3) Add 2 drops of 1% copper sulphate solution and mix. A mauve or purple colour develops if protein is present. *Sodium hydroxide solution can be used instead of potassium hydroxide solution.
