Aqueous solution of which of the following compounds is the best conductor of electric current?
Acetic Acid, C2H4O2
Hydrochloric Acid, HCl
Ammonia, NH3
Fructose, C6H12O6
In an Aqueous solution, HCl is the best conductor of electric current. Since HCl is a strong acid and hence it ionizes easily in an aqueous solution and provides free ions which are the carrier of electricity.
So, Option 2 is correct.
