Is crystallization of copper sulphate a physical change?
Yes: Crystallization of an already existing chemical substance is a physical change.
When water is added to white copper and copper sulphate why is it a chemical change?
oxidation
What do you get when you mix calcium and copper sulphate?
Calcium Sulphate + Copper
Is copper sulphate toxic?
no copper sulphate is not toxic it is flammable
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
Is copper sulphate a physical change or chemical?
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
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
Is crystallization of copper sulphate a physical change?
Yes: Crystallization of an already existing chemical substance is a physical change.
Why should copper sulfate dissolution be regarded as a chemical change?
Dissolution of Copper sulphate in water is a Physical Change... It cannot be regarded as a Chemical Change.
Does copper sulphate undergo any physical or chemical changes during heating?
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.
Is copper suphlate a mixture?
Copper Sulphate (check your spelling) is a chemical compound. It can only be separated by chemical change, not by physical change. Therefore, it is not a mixture.
When water is added to white copper and copper sulphate why is it a chemical change?
oxidation
What happens when copper sulphate is dissolved in water?
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
Iron plus copper sulphate equals iron sulphate plus copper - what change would you see on the surface of the nail?
The copper will appear on the surface of the nail, so it will be different in colour-it'll be like copper.
Chemical reaction between calcium and copper sulphate?
calcium + copper sulphate = calcium sulphate + copper hydroxide
Why aqueous copper sulphate solution conduct electricity but solid copper sulphate does not?
aqueous copper sulphate having high conductive hydroxide ions were as no in solid Copper sulphate.
Is copper oxide a reactant or product?
It can be either depending on the reaction. It can be a product of electrolysis of copper with sulfuric acid, or an acid base reaction of copper hydroxide and sulfuric acid. It can react with metals such as zinc.
