Respuesta :

Answer: The products of electrolysis are Zn(l) and [tex]Cl_2[/tex] gas

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.  

In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

[tex]ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-[/tex]

At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]

At cathode : [tex]Zn^{2+}(l)+2e^-\rightarrow Zn(l)[/tex]
