Question

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

Answer 1

Answer: $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

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.

$2NaCl(l)\rightarrow 2Na^++2Cl^-$

At anode : $2Cl^-(l)\rightarrow 2e^-+Cl_2(g)$

At cathode : $2Na^+(l)+2e^-\rightarrow 2Na(l)$

Answer 2

2Cl- (l) → Cl2 (g) + 2e-
