    1) why do copper 2 sulfate chrystals not conduct electricty?
    In the solid state, the ionic crystals can't move because they are aligned in a crystal lattice.

    2)why is copper 2 sulfate solution a good conductor of electricity?
    In the aqueous state, the crystal lattice is broken down and the copper ions and sulfate ions are free to move in the solution. Therefore, these ions can conduct an electrical current from one electrode to the other.

    3)why is water a poor conductor of electricity ,
    There are few ions present in pure water.
