The boiling point of pure copper is 2835K/2562C/4643F.
Copper Sulphate boils at 150 degrees C. water at 100 degrees C. So you can separate a mixture of the 2 using fractional distillation process.
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.
The percentage of water in copper(II) sulfate pentahydrate is 36,04 %.
You could place the copper sulfate solution in an evaporation dish and let the water evaporate at room temperature over a period of days.
of couse~ can.... even 2ml of water dissolve in 4.0 grams of copper 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.
Heat it in a crucible to a high temperature (well above the boiling point of water). Hydrated copper sulfate is blue in color; when it turns white you will know that the water has been driven out.
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?
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.

Why does copper sulfate change its colour when water is added
a copper sulfate solution it becomes copper (II) sulfate pentahydrate
Copper sulfate is soluble in water but doesn't react with water.
Nothing spectacular: a water solution of copper sulfate is obtained.
The percentage of water in copper(II) sulfate pentahydrate is 36,04 %.
Not much. The Copper (II) sulfate will just dissolve in the water (at about 316g/L of water). Copper (II) sulfate is pretty friendly around water and not all that dangerous. It's used commercially.
