Question
Give reasons for the following:
Copper is conducting as such while copper sulphate is conducting only in molten state or in aqueous solution.
Solution
Answer:
Copper sulphate conduct electricity only in molten state or in aqueous phase because on dissolving or melting it. copper sulphate dissociate in copper ion and sulphate ion and became free to move.
As they are freeto move in molten and aqueous phase the charge particle conduct electricity.
In solid and any other ionic form the ions held in a lattice and unable to move so they are not conduct electricity.
