MCQ
Solid sodium chloride is bad conductor of electricity because
- AIt contains only molecules
- BIt does not possess ions
- ✓The ions present in it are not free to move
- DIt does not contain free molecules
✓
Answer
Correct option: C.
The ions present in it are not free to move
c
(c)The ions are not free to move in solid state and held up in lattice due to strong coulombic forces of attraction.
(c)The ions are not free to move in solid state and held up in lattice due to strong coulombic forces of attraction.
