Question

Anhydrous hcl is bad conductor but in aqueous solution it is good conductor of current .Explain

Answer 1

anhydrous HCL H+ ions are less where as in aqueos Hcl H+ are more hence it is good conductor

Answer 2

For conduction of electricity we require either free electrons or charged ions . In anhydrous hcl there is none of above 2. But in aqueous solution hcl dissociate into H+ and Cl- ions so it becomes good conductor of electricity. i hope it helped
