Why can't you evaporate copper sulphate solution to separate copper sulphate crystals?

It is because the copper suphate chloride has a pH of 2334. This means crystals cannot be formed but instead hydrochloric methanical acid is formed. hydrochloric methanical acid is VERY harmful to us so kids: DON'T TRY THIS EXPERIMENT AT HOME!!
thank you,

How do you separate sand and copper sulphate and to obtain copper sulphate crystals in dry state?
copper sulphate is soluble.dissolve the two in water whereby cuso4 dissolves.filter the mixture the put the filtrate in an evaporating dish to evaporate excess water.do not evaporate to dryness coz some water ir required for crystalization.
How do you separate ammonium chloride and barium sulphate?
Add the mixture in water ammonium chloride is highly soluble in water while Barium sulphate is insoluble , filter the solution the residue(solid part) is Barium sulphate, evaporate the solution and get solid Ammonium chloride.
Why blue crystals of copper sulphate on heating turn colourless?
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.
How can you separate pure copper sulphate from an impure sample?
Dissolve in water and crystallize once more. The resulting crystals will be purer, while the remaining solution will comprise of the dopants + copper sulphate
Are copper sulphate crystals soluble?
Yes, in a saturated copper sulfate solution.
How do you separate Copper sulphate and broken glass?
Well copper sulphate crystals can be dissolved in water so when dissolved you filter the solution to remove the broken glass then evaporate the water then collect the crystals or crystallisation.

How do you separate chalk and copper sulfate?
Chalk (Calcium carbonate) is insoluble. Copper sulphate is soluble. To separate, first place the mixture in wter. The copper sulphate will dissolve, the chalk will not dissolve. When the copper sulphate is fully dissolved, filter the solution. The copper sulphate component will pass through the filter paper, but the chalk will remain in the filter paper. Dry the filter paper to obtain the dry chalk. Evaporate the solution to dryness, to obtain the blue dry copper sulphate crystals.
Are copper sulphate crystals soluble?
Yes, in a saturated copper sulfate solution.
What are examples of crystallisation where crystals can be grown?
take copper sulphate solution leave it for sometimes
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.
What can you get from evaporating copper sulphate?
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
What was left when water evaporates from copper sulphate solution?
Copper sulfate crystals remain in the container.
What equipment would be needed to prepare copper sulphate crystals?
Anhydrous or hydrated copper sulphate crystals? And from what?
