Which one of the following properties is not generally exhibited by ionic compounds?
(A) Solubility in water
(B) Electrical conductivity in solid state
(C) High melting and boiling points
(D) Electrical conductivity in molten state
Answer.:
- Ionic compounds conduct electricity with the help of the ions.
- When the negative and positive ions are free to move, they conduct electricity.
- When in solid state there are no free ions to conduct electricity.
- In aqueous or molten state, the electrons are free to move about, and hence they conduct electricity.
