Question

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

• A. water is good conductor of electricity
• B. hydrogen chloride gas dissociates in water
• C. a gas is an electrolnic conductor but a liquid is always an electrolytic conductor
• D. a gas does not obey Ohm's law whereas a solution does

Answer 1

The correct option is B hydrogen chloride gas dissociates in water

HCl gas ionizes in water solution and the ions so formed act as charge carriers.
