Is copper sulphate a physical change?
no
When water is added to white copper and copper sulphate why is it a chemical change?
oxidation
Why when blue salt copper sulphate is heated it becomes colourless?
Blue copper(II) sulfate (CuSO4), when heated, loses 5 water molecules per formula unit of water of crystallization. Its lattice structure collapses, giving it different physical properties, i.e. color.
Is crystallization of salt a physical change?
Assuming you're talking about salt forming as water evaporates: yes, that is a physical change. If you mean salt crystals forming from the combination of sodium and chlorine, then that's a chemical change.
What do you get when you mix calcium and copper sulphate?
Calcium Sulphate + Copper
Is copper sulphate a physical change?
no
What process obtain tiny particles copper sulphate from copper?
Crystallization
Can copper sulphate be separated from its solution by crystallization?
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
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
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.
Heating Hydrated Copper Sulphate?
On heating hydrated Copper Sulphate (CuSO4 . 5 H2O), the result is the removal of water molecules of crystallization, which for this very compound is 5 molecules per molecule of copper sulphate. The process cited above is termed as dehydration.
