Heating copper sulfate crystals causes the water molecules within the crystal to be driven off. This removes the water of hydration, leaving behind anhydrous copper sulfate, which is white in color. The blue color of the crystal is due to the presence of water molecules, so removal of water results in the disappearance of the blue color.

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
Why colour of copper sulphate crystals changes on heating?
The color change of copper sulfate crystals on heating is due to the loss of water molecules from the crystal lattice. The blue color of hydrated copper sulfate is due to the presence of water molecules within the crystal structure. When heated, these water molecules are driven off, leading to a white color (anhydrous copper sulfate) as the crystal becomes dehydrated.
What is the colour of paint after heating copper sulphate?
The color of paint after heating copper sulfate will change from blue to white as the heat drives off the water molecules in the compound.
What is the colour of aqueous solution of ferrous sulphate?
The aqueous solution of ferrous sulphate is typically pale green in color.
What colour is anhydrous copper sulphate once heated?
Hydrated copper sulphate (CuSO4.5H2O) is BLUE Anhydrous copper sulphate (CuSO4) is white at any temperature.
What is the colour of ferrous sulphate crystal?

Why does the blue colour of copper sulphate disappear when a zinc plate is dipped into it?
The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.
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 .

What is the colour of aluminium sulphate solutions?
aluminum sulphate is colourless
What is Colour of cobalt sulphate?
pink
What is the colour of the solution if zinc is added to copper sulphate solution?
No colour
What color is copper sulphate solution and water mixture?
Copper sulphate's colour is blue.
What is the colour of the crystales of copper sulphate?
Blue
Why does magnesium displace copper from copper sulphate?
This is a simple displacement reaction - the more reactive magnesium displaces the less reactive copper from a solution of its salt. .... magnesium + copper sulphate ---> copper + magnesium sulphate Mg + CuSO4 ----> MgSO4 + Cu the blue colour of the copper sulphate will disappear and the silver coloured magnesium will be replaced by brown-red copper metal. Hope this helps. :)
Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
