Question

During Electrolysis of NaCl,

NaCl is taken in molten state so it conducts eletricity because of the free electrons, so why are the free electrns present only in its molten state and not in its solid state and therefore resulting in soid NaCl not conducting electricity.

Answer 1

In order to conduct electricity a substance must have charge particles, such as electrons and ions, that are free to move freely through it. In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
