The substance turns white then grey and finally brown. That is because heat is given off and water evaporates.

What is the balanced equation when copper ll sulfate pentahydrate is heated?
cuso4 - 5h2o= cuso4 + 5h20 + heat
What happens when you heat anhydrous copper sulphate?
Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate. When you heat copper sulfate pentahydrate it turns white as the water which is driven off by the heat. The white solid remaining is anhydrous copper sulfate. If you add water to the anhydrous copper sulfate an exothermic reaction occurs, you can feel the test-tube getting hot, as the blue copper sulfate pentahydrate is re-formed.
Balance Copper 2 sulfate pentahydrate is heated to drive off the water hydration?
penta = 5 copper(II) sulphate pentahydrate = CuSO4*5 H2O CuSO4*5 H2O + heat --> CuSO4 + 5 H2O
When hydrated copper sulfate is heated it loses its water of hydration and becomes what?
It becomes a non-crystalline, powdery anhydrous salt.The hydrated (pentahydrate) form is chalcanthite, a bright blue crystal. The rare anhydrous ore form is called chalcocyanite, a gray or pale-green powdery rock.(If heated to 650 °C, copper sulfate becomes copper oxide and sulfur trioxide.)
What is the chemical equation for he reaction of copper sulfate when heated?
Copper sulfate in its solid crystal from present as pentahydrate (CuSO4 5 H2O). When heated strongly it loses water molecules and becomes CuSO4. Note that CuSO4 5 H2O is blue in color whereas CuSO4 is colourless since absorption region shifted from visible region. On further heating it is dissociated to CuO.
What chemical reaction occurred copper sulfate pentahydrate when heated?
The chemical decomposition is:CuSO4------ CuO + SO3
What is the balanced equation when copper ll sulfate pentahydrate is heated?
cuso4 - 5h2o= cuso4 + 5h20 + heat

Why does copper II sulfate pentahydrate lose its blue colour once heated?
The 5 water molecules are driven off by heating and the central Copper atom is no longer complexed by the water molecules which affects the energy and hence the color of the resulting anhydrous Copper Sulfate.
When hydrated copper sulfate is heated it loses its water of hydration and becomes copper sulfate?
It becomes a non-crystalline, powdery anhydrous salt.The hydrated (pentahydrate) form is chalcanthite, a bright blue crystal. The rare anhydrous ore form is called chalcocyanite, a gray or pale-green powdery rock.(If heated to 650 °C, copper sulfate becomes copper oxide and sulfur trioxide.)
When Copper Sulphate is heated what is the observation?
When copper sulfate is heated the observation is that it turns white as the water which is driven off by the heat. It is also stated that the white solid will remain and if water is added to the anhydrous copper sulfate a reaction will occur.
Suppose 2.3754g of copper-II sulfate pentahydrate is heated to drive off the water of crystallization Calculate what mass of anhydrous salt will remain?
The gram formula unit mass of copper (II) sulfate pentahydrate is 249.68. The gram formula unit mass of water is 18.015. Therefore, the mass of water of crystallization present in 50.0 g of copper (II) sulfate pentahydrate is: 50[5(18.015)/249.68] or 18.0 g, to the justified number of significant digits. (Note that the prefix penta- means five)
When hydrated copper sulfate is heated it loses its water of hydration and becomes what?

What would happen if copperIIsulfate crystals was heated to dryness?
It would form a white substance called anhydrous copper(II) Sulfate. *Anhydrous - Salts that do not contain water. Copper (II) sulfate pentahydrate is also called "blue vitriol," because it's, well, blue (vitriol is an old term for sulfuric acid). However, anhydrous copper (II) sulfate is white.

What happen when sulfur is heated with copper wire?
Copper sulfate is formed.
