Why blue crystals of copper sulphate on heating turn colourless?
The formula of the blue crystals of copper sulphate is CuSO4.5H2O. When they are heated mildly, the water from the crystals evaporate, giving just CuSO4. This 'anhydrous' form of copper (II) sulphate is white in colour.
What is the colour of ferrous sulphate crystal?
The color of ferrous sulphate crystals is green. However on heating, it yields a brownish mass ( as water is lost) and on further heating they lead to release of a mixture of sulfur dioxide and sulfur trioxide
What is the color of ferrous sulphate crystals?
It is pale green in colour.
What colour is anhydrous copper sulphate once heated?
Anhydrous copper sulfate is white powder, heating makes no difference.
What two colour changes do you get when you add copper sulphate solution to iron wool?
black and yellow black and yellow
What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .

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.

Why colour of CuSO4 crystals changes on heating?
The blue copper sulfate pentahydrate loss by heating water and become an anhydrous white sulfate.
What colour are copper sulphate crystals?
very dark blue
What is the color of ferrous sulphate crystals?
It is pale green in colour.
If you heat the ferrous sulphate crystals in dry boiling tubewhat color you get?
brown colour
Why does the color with sulphate change?
This is because sulphate is a thing that just dissolve in the water and changes the colour.
How can anhydrous salt changes into their hydrated salt?
On heating, hydrated salts lose their water of crystallization and as a result, the crystals lose their shape and colour and change to a powdery substance.
Why do you use copper sulphate?
A rather incomplete question. I could use copper sulphate for a number of reasons, for example as an electrolyte for copper plating, as a medium for growing impressive deep blue crystals, as a fungicide and so on. For fun, try dropping some iron filings into a fairly concentrated solution of copper sulphate and observe how the iron filings change to a copper colour and the solution changes to a green colour.
When mixed with water why does copper sulphate turn water blue?
because when in a solution it forms blue crystals creating a blue colour
