Blue Copper sulphate crystals contain a lot of water. If you heat them the water is driven off and they turn white.

What happens when you heat copper sulfate crystals?
they get warmer Blue Copper sulphate crystals contain a lot of water. If you heat them the water is driven off and they turn white.
What happens when you heat hydrated copper sulfate?
The blue hydrated CuSO4 turns pale white, when dehydrated.
What happen if add heat to anhydrous copper sulfate?
Copper sulfate can be thermally dissociated at apptox. 500 oC.
What happens if you heat copper?
If you heat copper it will oxidise and therefore lose electrons.
What happens if you add zinc to copper sulfate And what happens if you add gold to copper sulfate?
Adding zinc to copper sulfate will result in a displacement reaction that will create copper metal to precipitate as a solid. CuSO4(aq) + Zn(s) ---> ZnSO4 + Cu(s) This reaction is quite exothermic too, meaning it will give off alot of heat - enough to make it too hot to hold the reaction beaker in bare hands.
What happens when you heat anhydrous copper sulphate?
Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate. When you heat copper sulfate pentahydrate it turns white as the water which is driven off by the heat. The white solid remaining is anhydrous copper sulfate. If you add water to the anhydrous copper sulfate an exothermic reaction occurs, you can feel the test-tube getting hot, as the blue copper sulfate pentahydrate is re-formed.

How do you separated the copper sulfate from water?
Heat it

Does a change in color observed when copper II sulfate crystals become dehydrated how do you account for the change when water is added to the heated copper II sulfate?
Yes, copper (II) sulfate, also known as cupric sulfate, is a deep blue when it is hydrated (when it has water). If you heat it, the water evaporates and leaves plain copper (II) sulfate power, which is a cream color. So yes, dehydrating copper (II) sulfate in its hydrated form will cause it to change from blue to white. If you take this dehydrated (anhydrous) copper (II) sulfate and add water to it, it will become hydrated again, so the white powder will, once again, turn that deep blue color.
What would happen if copper sulfate evaporated?
Copper sulfate would crystalize as blue crystals, water would evaporate. To get the copper sulfate itself to evaporate you would need to heat it, melting the dry crystals then vaporizing them.
What happens when you heat copper hydroxide and sodium nitrate?
When heat copper hydroxide and sodium Nitrate the pale blue precipitate change into black solid
What kind of chemical reaction do you get when you heat copper sulfate pentahydrate?
The reaction is dehydration.
What happens if you heat copper?
If you heat copper it will oxidise and therefore lose electrons.
What happens when you heat copper in oxygen?
copper oxide
How Benedict's solution react with sugar?
Sugar donates electrons that reduce blue copper (II) sulfate to orange copper (I) oxide.
