Why carbon electrodes are used in the electrolysis?
The solution of electrolysis contains two rods. Each of them carries different chemical or physical reactions when current is passed through the solution. Then positively charged ions flow towards cathode since it receives electrons. On the other side, the negatively charged ions move towards positive ones or anode and loss electron. Usually, it is made out of an allot rope of carbon compound called graphite. They are made from joining many carbon atoms in a hexagonal shape and linked with more number of hexagonal to make a layer and it will be one atom thick.
