When water is added to white copper (zinc) and copper sulfate, a chemical change occurs because new substances are formed. The zinc displaces the copper in the copper sulfate solution, leading to the formation of zinc sulfate and copper metal, which are chemically different from the original substances. This reaction is a classic example of a single displacement reaction.

What is the chemical equation for when iron is added to copper sulphate iron sulphate is formed and copper falls to the bottom?
The chemical equation for this reaction is: Fe(s) + CuSO4(aq) -> FeSO4(aq) + Cu(s).Iron displaces copper from copper sulphate solution to form iron sulphate and solid copper precipitates out of the solution. This is an example of a single displacement reaction.
When water is added to copper sulphate powder it becomes hot and blue this is a chemical change why?
When water is added to copper sulfate powder, a chemical reaction occurs that releases energy in the form of heat, making the mixture hot. The blue color observed is due to the formation of a complex ion called copper(II) aqua complex. This color change and heat production indicate a new substance is formed, making it a chemical change.
What happens to copper sulphate when added to water?
When copper sulphate is added to water, it dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water.
Copper sulphate add to sodium hydroxide result colour?
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
Does copper sulphate dissolved in water?
Yes, copper sulphate can dissolve in water. When added to water, copper sulphate dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-), forming a blue-colored solution.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
What chemical should be added to copper carbonate to make copper sulphate?
Sulphuric acid, because "sulphuric" is what gives copper sulphate it's name

What happens when copper is added to copper sulphate?
Nothing
What two things happen when zinc is added to copper sulphate?
The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!
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 happens to copper sulphate when added to water?
When copper sulphate is added to water, it dissociates into copper ions (Cu2+) and sulphate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water.

What salt did you make whenn you added copper carbonate to sulfuric acid?
When copper carbonate is added to sulfuric acid, it produces copper sulfate, carbon dioxide gas, and water. The balanced chemical equation is: CuCO3 + H2SO4 → CuSO4 + CO2 + H2O.
Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
Yes, copper sulfate can be prepared from copper metal and dilute sulfuric acid through a chemical reaction known as copper displacement. When copper metal is added to dilute sulfuric acid, it reacts to form copper sulfate along with the release of hydrogen gas.
