What happens when steel wool is added to copper sulphate?
Copper is deposed on the steel wool.
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
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 happens to copper sulphate when heated?
When copper sulfate is heated, it undergoes thermal decomposition, turning into copper oxide, sulfur dioxide gas, and oxygen gas. The color of the compound changes from blue to black as the heating process progresses.
Zinc plus Copper sulphate?
When zinc is added to copper sulfate, a displacement reaction occurs where zinc displaces copper from the compound to form zinc sulfate and copper metal. The balanced chemical equation is: Zn + CuSO4 -> ZnSO4 + Cu. The copper metal will appear as a reddish-brown precipitate while the zinc sulfate solution will remain colorless.
What happens when copper is added to copper sulphate?
Nothing
What would happen if you added copper sulphate to water at room temperature?
Copper sulfate is soluble in water and dissociated in ions (Cu2)+ and (SO4)2-.
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.
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.
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 steel wool is added to copper sulphate?
Copper is deposed on the steel wool.
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!!!!!!!!!!!
Does copper sulphate dissolve in oil?
No. All metal sulphate are soluble in water, except barium sulphate, calcium sulphate and lead sulphate.
Why does one of the reactant copper carbonate is added in excess when preparing a sample of copper sulphate crystals?
Excess copper carbonate is added to ensure that all the copper sulphate is fully converted. This helps to make sure that all the starting material is used up and that the reaction goes to completion, resulting in a higher yield of pure copper sulphate crystals.
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
What happens when copper is added to concentrated sulfuric acid and heated gently?
copper sulphate and hydrogen is released.
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.
