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.)

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
Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
What elements make up copper sulfate?
The elements in copper sulphate are copper, sulphur and oxygen. Copper sulphate is a compound, made up of three elements. The symbol for this compound is CuS04.
Does a change in color observed when copper II sulfate crystals become dehydrated how do you account for the change when water is added to the heated copper II sulfate?
Yes, copper (II) sulfate, also known as cupric sulfate, is a deep blue when it is hydrated (when it has water). If you heat it, the water evaporates and leaves plain copper (II) sulfate power, which is a cream color. So yes, dehydrating copper (II) sulfate in its hydrated form will cause it to change from blue to white. If you take this dehydrated (anhydrous) copper (II) sulfate and add water to it, it will become hydrated again, so the white powder will, once again, turn that deep blue color.
What is the formula for hydrated copper II sulfate?
Copper sulfatepentahydrate is a solid at 20 degrees Celsius has a density of 2.28g/cm3 (cubed)... and its' chemical symbol is CuSO4-5H2O

Is copper sulfate black?
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
Is dehydration and hydration of copper sulfate reversible?
Dehydration and hydration of copper sulfate certainly is reversible. This is because the process can happen and be reversed and happen again.
Hydrated forms of copper sulfate?
The primary hydrate of copper sulfate is the pentahydrate of copper (II) sulfate, with formula CuSO4.5 H2O.
What is the chemical symbol for hydrated copper sulfate?
10h2o.Cuso4
How many moles of anhydrous copper sulfate is produced when 6.4 moles of hydrated copper sulfate is heated?
1020g

What is the chemical formula for Anhydrous?
The term anhydrous means without water. Some compounds, such as copper sulfate (CuSO4) have the capacity to absorb water, which becomes loosely attached to the ionic compound, at which point it is said to be hydrated; if you heat it you can drive off the water, at which point it becomes anhydrous. Hydrated copper sulfate is blue in color; the anhydrous form is white.
If solid copper sulfate is mixed with water what is formed?
a copper sulfate solution it becomes copper (II) sulfate pentahydrate
What happens when you heat hydrated copper sulfate?
The blue hydrated CuSO4 turns pale white, when dehydrated.
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.
