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
Answers (1)
Ans. (b)
Properties of ionic compounds:
- Can conduct electricity in molten or aqueous state only.
- High melting and boiling points
- Most ionic compounds are soluble in water and form aqueous solutions.
- In solid state, these are non-conductor of electricity because of the absence of free ions.
- The ions are held together in fixed position by strong electrostatic force and cannot move freely.
Hence, electrical conductivity in solid state is not generally exhibited by ionic compounds.
Therefore option (B) is correct
