If molten magnesium bromide (mgbr) is split by electrolysis, which of the following reactions occurs at the anode?

question 1 options:

2br2 (g) --> 2br (l) + 2e-

2mg+ (l) --> 2mg+ (l) + 2e-

2br- (l) --> br2 (g) + 2e-

2mg+ (l) + 2e- --> 2mg (l)

Answer : The correct option is,

Explanation :

Electrolytic cell : It is defined as the cell in which the chemical reaction occurs by passing of the current from external source.

In this electrolytic cell, the oxidation occurs at anode which is a positive electrode and reduction occurs at cathode which is a negative electrode.

For example : On passing electricity in the molten .

The two half-reaction equation are :

Reduction :    (cathode)

Oxidation :      (anode)

The balanced chemical reaction will be,

Hence, the correct option is,

hope this !
