Pure:
CuSO4(H2O)5Copper Sulfate CuSO4 or Cu2SO4 is a chemical compound which can only be broken down by chemical means, so yes it is a pure substance.
Copper wire is a pure substance, as it is made entirely of copper atoms.
To prepare copper sulfate, dissolve copper oxide or copper metal in sulfuric acid. Then, evaporate the solution until crystals of copper sulfate start to form. Finally, filter and dry the crystals to obtain pure copper sulfate.
The solute is copper sulfate, as it is the substance being dissolved in water.
