Q. It has been observed that gaseous hydrogen chloride is a very poor conductor of electricity but a solution of hydrogen chloride gas in water is a good conductor of electricity. This is due to the fact that:
- water is good conductor of electricity
- hydrogen chloride gas dissociates in water
- a gas is an electrolnic conductor but a liquid is always an electrolytic conductor
- a gas does not obey Ohm's law whereas a solution does
