प्रश्न
How is it that ionic compounds in the solid state do not conduct electricity but they do so when in molten state?
उत्तर
The ionic compounds in solid state are bonded with strong intermolecular forces and are not free to move. Therefore, they cannot conduct electricity. However, when this salt melts, its constituent ions are separated from each other and become free to move across the melted salt that can conduct electricity.
