Electrolysis of Brine

The video explains the electrolysis of brine, a process that separates sodium chloride into useful products like hydrogen, chlorine, and sodium hydroxide. It details the reactions at the anode and cathode, where chlorine and hydrogen gases are formed, respectively. The video also highlights the industrial applications of these products, such as in cleaning and water treatment.

What is the main purpose of using carbon electrodes in the electrolysis of brine?

• To produce more chlorine gas

• To enhance the conductivity of the solution

• To prevent the electrodes from reacting
