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
- Hydrogen chloride gas in water solution ionizes
- A gas is non-conductor but a liquid conducts electricity
- Gas does not obey Ohm's law whereas solution does
- Water is good conductor of electricity
