Answer Details
CuSO45H2O can be obtained from an aqueous solution of copper (II) tetraoxosulphate (VI) by **crystallization**. Crystallization is the process of separating a solid substance from a liquid by cooling the liquid or allowing it to evaporate slowly. In this case, by slowly evaporating the water from the solution of copper (II) tetraoxosulphate (VI), CuSO45H2O will crystallize out of the solution as blue crystals. The crystals obtained will have a definite shape and size, and can be filtered and dried to obtain the pure solid CuSO45H2O.
