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.

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 Hydrated copper sulfate crystals cannot be obtained from a solution by direct heating?
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
What two ways can speed up the rate of dissolving copper sulphate in water?
1. Increase the temperature of the water. 2. Use copper sulphate in the finely powered form instead of copper sulphate crystals (if hydrated). 3. Stir.
What is The name of the copper sulphate after being heated?
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
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 hydrated copper sulphate increase the mass?
Hydrated Copper Sulphate is CuSO4.5H2O and Anhydrous copper sulphate is just CuSO4. Therefore, hydrated copper sulphate has extra mass due to water molecules present in it.
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.
How copper sulphate diffuse in water?
copper sulphate gets hydrated in water and thus is diffusible.
What is a reversible chemical reaction for the heating of hydrated copper sulphate?
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
What equipment would be needed to prepare copper sulphate crystals?
Anhydrous or hydrated copper sulphate crystals? And from what?
How do you remove colour from copper sulphate using anhydrous?
The hydrated copper sulfate (blue color) become white after heating and releasing of water; the white anhydrous copper sulfate is obtained.
What is the Formula of hydrated copper sulphate?
CuSO4
What gas or liquid if any would you get if you heated hydrated copper sulphate?
You would get water in the gas phase (steam). The word "hydrated" means that there are water molecules mixed in with the copper sulphate, and so when you heat it, you will turn that water into steam, freeing it. Because of the high melting point of ionic compounds like copper sulphate, it will not be affected by heating unless you go to extemely high temperatures.
What colour is hydrated copper sulphate?
it is bright pink!
What do you observe when copper sulphate crystals are heated?
With sufficient heating, the blue colored hydrated copper sulfate crystals common at standard temperature and pressure will lose their water of hydration and lose their blue color. With further heating, the anhydrous crystals will melt.
Why Hydrated copper sulfate crystals cannot be obtained from a solution by direct heating?
Heating the saturated solution of Copper sulfate will not form the hydrated copper sulfate crystals because only after cooling down the saturated solution of copper sulfate then only the crystals of the hydrated copper sulfate can be formed
What is difference between sulphides and sulphates?
copper sulfate's chemical symbol is actually CuSO4 ... the symbol CuSO4-5H2O is copper sulfate pentahydrate... someone should edit the answer on CuSO4 copper sulfate
