Question

why solid nacl is bad conductor and in aquoes solution nacl is good conductor

Answer 1

Answer:

because solid NaCl does not dissociate ions

where as solution of NaCl dissociate ions which helps in conduction

Answer 2

bcaz in solid it can't able to conduct electricity ,ions are not able to move ,so charge not move ,

but in aqua solution ions of NaCl can go to their respective electrodes and conduct electricity so it is good conductor in aqueous solution
