Why solid NaCl does not conduct electricity but in molten form is conducted electricity?
In solid-state, there is very close and very strong bonding in an anion and a cation. due to opposite charges and complete transferring there is no free electron to conduct the electricity. but in molten form or in an aqueous medium there is a weak bond in them due to the dielectric property of water. dielectric property of water converts a strong bond into a weak bond so ions formation takes place so electricity is conducted in the aqueous media.
