Solid sodium chloride does not conduct electricity while sodium chloride solution conducts. Explain why.

Solid sodium chloride does not conduct electricity while sodium chloride solution conducts because:

i. As we all know that when free electrons are available only then electricity is conducted.


ii. In solid sodium chloride, electrons are not able to move freely. They are holding tightly each other and stacked over one other.


iii. On the other hand, in solid chloride solution, electrons can move freely. They are loose. Due to this property, sodium chloride solution conducts electricity.
