Question

Sodium crystal of sodium chloride does not conduct electricity but aqueous solution of sodium chloride conducts electricity? why?

Answer 1

Answer :

A substance has charged particles, like electrons and ions, that are free to move freely through it can only conduct electricity.

Solid Sodium chloride has their ions fixed in position in a crystal structure hence ions cannot move so solid ionic compounds cannot conduct electricity.

But in molten state ions are free to flow and therefore in molten state sodium chloride can conduct electricity.

Answer 2

because the aqueous solution is consist water molecules which gets break into cation and anion, it's conduct electricity. but crystal don't have ion so it doesn't conduct electricity.
