In summary, Pyrovus states that hydrochloric acid is a Bronsted acid and will dissociate in water to create free and mobile ions, which will cause it to conduct electricity.

Of course; HCl is an ionic solid; by definition, ionic solids are composed of anions and cations; when the solid is made liquid, you have free and mobile ions; thus, you can conduct electricity.
Yes, pure molten HCl will conduct electricity

Well, I am not sure; hydrochloric acid is a gas which is used as aqueous solution. In high temperature you will not get it as a solid; it will evaporate. However, high temperature will possibly help its ionization.

Would not the HCl gas conduct electricity as well? It has ions more mobile than that of its liquid form

Liquid HCl will probably be a poor conductor of electricity owing to the fact that it is a covalent compound and doesn't have terribly many ions floating about. Pure water will conduct electricity as a result of ions created by the reaction 2H2O <-> H3O+ + OH-, and there is probably an analagous equilibrium taking place with the HCl: 2HCl <-> H2Cl+ + Cl-. However, HCl is such a weak base that it will have little tendency to accept a proton to form H2Cl+, so this reaction will probably have very little effect (also it should be noted that pure water is still a poor conductor of electricity, even with the aforementioned equilibrium taking place).

Silly mE!
I forgot it was covalent... !Ay!

How? HCl is hydrochloric acid!, and it is a strong acid! Strong acids will dissociate well in water! Which means mobile ion availability in aqueous HCl solutions!--and thus will conduct electricity!

What Pyrovus means is that in the reaction [tex]2HCl \leftrightarrow H_2Cl^+ + Cl^-[/tex] HCl plays role of proton acceptor - so it is a Bronsted base.

1. How does molten hydrochloric acid conduct electricity?
Molten hydrochloric acid conducts electricity due to the presence of ions in the solution. When hydrochloric acid is melted, it dissociates into positively charged hydrogen ions (H+) and negatively charged chloride ions (Cl-). These ions are free to move and carry electric current.
2. Can pure molten hydrochloric acid conduct electricity?
Yes, pure molten hydrochloric acid can conduct electricity. As mentioned before, when hydrochloric acid is melted, it dissociates into ions which are responsible for conducting electricity.
3. How does the concentration of molten hydrochloric acid affect its conductivity?
The concentration of molten hydrochloric acid affects its conductivity. Higher concentrations of hydrochloric acid have more ions present, therefore allowing for a higher conductivity compared to lower concentrations.
4. Is molten hydrochloric acid a good conductor of electricity?
Molten hydrochloric acid is a good conductor of electricity. It has a high conductivity compared to other molten ionic compounds due to the strong attraction between the hydrogen and chloride ions.
5. Can impurities in molten hydrochloric acid affect its conductivity?
Yes, impurities in molten hydrochloric acid can affect its conductivity. Impurities can disrupt the dissociation of hydrochloric acid into ions, therefore decreasing its conductivity.
