  • question_answer   Why do ionic compounds conduct electricity in molten state?          [CBSE Delhi 2008C]

    Answer:

                      In solid state, ionic compounds do not conduct electric current because the ions are held together in fixed positions by strong electrostatic forces and cannot move freely. When ionic solid is dissolved in water or melted, the crystal structure is broken down and ions become free to move and conduct electricity.
