1.	Except one state of the following, Ionic compounds do not allow the transmission of electricity through them? A. Solid state. B. Liquid state. C. Gaseous state. D. All of the above.
Answer» Ionic compounds do not conduct electricity in solid state. Because , Absence of MOBILE ions in solid stateReason Ions in an ionic lattice are fixed at their POSITIONS and can only oscillate about their mean positions. HENCE, in the solid state, the ions are not free to move. While in molten form, these ions can freely move in the SOLUTION which also allows the passage of electricity. The right reason is the absence of mobile ions in the solid state.
