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 else can I help you with?
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 colour does hydrous copper sulphate turn when heated?
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
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.
When crystals of ferrous sulphate are strongly heated residue obtained is in which colour we get?
The residue obtained when crystals of ferrous sulphate are strongly heated is reddish-brown in color. This residue is a compound called ferric oxide or iron(III) oxide.
What is the color of ferrous sulphate crystals?
Ferrous sulphate crystals are typically white or colorless in their pure form. However, they can oxidize and turn green upon exposure to air due to the formation of iron oxide.
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 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 colour are copper sulphate crystals?
very dark blue
Why colour of CuSO4 crystals changes on heating?
The blue copper sulfate pentahydrate loss by heating water and become an anhydrous white sulfate.
If you heat the ferrous sulphate crystals in dry boiling tubewhat color you get?
brown colour
What colour does hydrous copper sulphate turn when heated?
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.

Does copper sulphate undergo any physical or chemical changes during heating?
When heated, copper sulfate undergoes a reversible physical change where it loses its water molecules (dehydration) and changes color from blue to white. This process is purely physical and does not involve any chemical reactions.
What is the color of ferrous sulphate crystals?
Ferrous sulphate crystals are typically white or colorless in their pure form. However, they can oxidize and turn green upon exposure to air due to the formation of iron oxide.
When crystals of ferrous sulphate are strongly heated residue obtained is in which colour we get?
The residue obtained when crystals of ferrous sulphate are strongly heated is reddish-brown in color. This residue is a compound called ferric oxide or iron(III) oxide.
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.
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.
