The electrolysis of aqueous sodium chloride (brine) is an important industrial process for the production of chlorine and sodium hydroxide. In fact, this process is the second largest consumer of electricity in the United States, after the production of aluminum. Write a balanced equation for the electrolysis of aqueous sodium chloride (hydrogen gas is also produced).

The electrolysis of aqueous sodium chloride (brine) is an important industrial process for the production of chlorine and sodium hydroxide. In fact, this process is the second largest consumer of electricity in the United States, after the production of aluminum. Write a balanced equation for the electrolysis of aqueous sodium chloride (hydrogen gas is also produced).
Interpretation Introduction
Interpretation: The balanced equation for the electrolysis of aqueous sodium chloride is to be stated.
Concept introduction: The process of decomposition of compounds by passing electricity through a solution is known as electrolysis.
To determine: The balanced equation for the electrolysis of aqueous sodium chloride.
Explanation of Solution
Explanation
The sodium chloride is decomposed into sodium ion and chlorine ion by electrolysis. Two electrodes are inserted into the solution and electric current is passed through it. The sodium ion is collected at one of the electrode (cathode) and chlorine ion is deposited at anode.
The reaction at cathode is,
The balanced equation at cathode is,
The reaction at anode is,
