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 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.


What do copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled?

Copper sulphate crystals form when a hot saturated solution of copper sulphate is cooled down. As the solution cools, the solubility of copper sulphate decreases, causing the excess copper sulphate to come out of the solution and form crystals.


Can Copper Sulphate crystals dissolve?

Yes, Copper Sulphate crystals can dissolve in water to form a blue solution.


What do you get when you evaporate a copper sulphate solution?

You'll get first: blue Cu-sulfate pentahydrate crystall's and after further heating: white anhydrous Cu-sulfate powder.


What substance changes blue anhydrous copper sulphate crystals to white?

Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.


When blue salt of copper sulphate is heated it becomes colourless why?

actually blue salt of copper sulphate is chemically copper sulphate penta hydrate( CuSO4.5H2O ). blue coloure is due to thiese 5 moles of water . by heating this water evaporates and leaving CuSO4 which is colourless


What equipment would be needed to prepare copper sulphate crystals?

To prepare copper sulfate crystals, you would need a heat source, glassware such as beakers and stirring rods, distilled water, copper oxide or copper sulfate powder, a balance for measuring mass, and a filtration setup for separating the crystals from the solution. Optional equipment includes a thermometer for temperature monitoring and a hot plate for heating.


Do copper sulphate crystals have cleavage planes?

No, copper sulphate crystals do not have cleavage planes because they are not considered minerals with cleavage. Cleavage is the tendency of a mineral to break along specific planes due to its crystal structure, which copper sulphate does not exhibit. Instead, copper sulphate crystals tend to break irregularly along their structure.


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


How will you obtain pure copper sulphate crystal?

boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.
