Question

Commercial electrolysis is performed on both molten NaCl and aqueous NaCl solutions. Identify the anode product, cathode product, species reduced, and species oxidized for the(a) molten electrolysis

Answer 1

The anode product is Cl2 (g) , the cathode product is Na (l) metal , the species that is getting reduced is Na+ (l) and the species that is getting oxidised is Cl- (l)

What is Electrolysis ?

Electrolysis is a process that involves the movement of ions to the oppositely charged cathodes.

For example: electrolysis of NaCl.

Electrolysis of NaCl : The commercial electrolysis of NaCl is performed on both molten NaCl and aqueous NaCl solutions.

What is Electrolysis of molten NaCl ?

1. When NaCl is heated at very high temperature ≈1070 K, it gets separated into ionised forms i.e. sodium ion and chloride ion.

The following reaction takes place:

NaCl (l)   →  Na+ (l) + Cl-(l)

2. During electrolysis the following reactions takes place at cathode and anode respectively:

at anode: 2Cl- (l)  →  Cl2(g) + 2e-

at cathode: 2Na+ (l) + e-   →   Na(l)

Overall reaction is :

2Na+(l) + 2Cl-(l)  →  2Na(l) +  Cl2 (g)

So, from the above reactions the following conclusions can be drawn :-

The product obtained at anode is Cl2 (g) and the product obtained at cathode is Na(l) metal. The species that is getting oxidised is Cl- (l) and the species that is getting reduced is Na+ (l) metal.
