Why does copper II sulfate pentahydrate lose its blue colour once heated?
Megan1023
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.

What chemical reaction occurred copper sulfate pentahydrate when heated?
The chemical decomposition is:CuSO4------ CuO + SO3
What colour is anhydrous copper sulphate once heated?
Anhydrous copper sulfate is white powder, heating makes no difference.
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)
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
1020g
What happens if Copper Sulphate penta-hydrate is heated?
Copper sulphate pentahydrate loses water of crystallisation and becomes white amorphous anhydrous copper sulphate.
What is the balanced equation when copper ll sulfate pentahydrate is heated?
cuso4 - 5h2o= cuso4 + 5h20 + heat
What chemical reaction occurred copper sulfate pentahydrate when heated?
The chemical decomposition is:CuSO4------ CuO + SO3
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
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.
Copper II sulfate pentahydrate reaction when heated?
The substance turns white then grey and finally brown. That is because heat is given off and water evaporates.
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.)
What colour is anhydrous copper sulphate once heated?
Anhydrous copper sulfate is white powder, heating makes no difference.

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.
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
1020g
