Question

which method of separation would you use to separate copper sulphate crystals from its solution ? why cant,t you evaporate the solution ?​

Answer 1

Answer:

i hope this helps you:

Separating solids from liquids- we use evaporation because Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution.

Answer 2

The method of separation depends on which compound it is mixed with.

In many salt preparations its important not to completely dry the crystals because some might decompose on further heating. Copper sulfate is an example and you should not evaporate this solution to complete dryness.

I hope that it will be helpful to you.
