What is the chemical equation for when iron is added to copper sulphate iron sulphate is formed and copper falls to the bottom?
Fe = CuSO4 ----> FeSO4 + Cu
When water is added to copper sulphate powder it becomes hot and blue this is a chemical change why?
This is generally regarded as a chemical change, as is usually indicated by a color change and/or the evolution of heat. The added water forms bonds to the copper ions in the copper sulphate powder, the bonds being of a type known as"coordinate" or sometimes "coordinate-covalent". Since these bonds are weaker than most chemical bonds, some chemists might deny that a chemical reaction has occurred.
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
What salt did you make whenn you added copper carbonate to sulfuric acid?
copper sulphate
What is observed when copper oxide is added into excess dilute sulphuric acid?
Copper sulphate + water
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
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
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 salt did you make whenn you added copper carbonate to sulfuric acid?
copper sulphate
What happens when steel wool is added to copper sulphate?
Copper is deposed on the steel wool.
Does copper sulfate have a concentration?
A copper sulphate solution can have different concentrations depending on how much copper sulphate crystals have been added into the water. A typical 1 molar solution of copper sulphate would need 250g of CuSO4, mixed with 700ml of H2O, with 10ml of H2SO4 added with another 290ml of water.
What happens to copper sulphate when heated?
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
