If molten sodium chloride is split by electrolysis, which reaction occurs at the anode?

2Cl2 (g) →2Cl− (l) + 2e−


2Cl− (l) →Cl2 (g) + 2e−


2Na (l) →2Na+ (l) + 2e−


2Na+ (l) + 2e−→2Na (l)

Respuesta :

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

Explanation:

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

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

[tex]2NaCl(l)\rightarrow 2Na^++2Cl^-[/tex]

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

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

2Cl- (l) → Cl2 (g) + 2e-
