Why are carbon electrodes neutral in electrolysis of water?

In summary, carbon electrodes are used in electrolysis of water because they are inert, inexpensive, and readily available. They remain neutral in the process as they only act as conductors for the electric current. Other types of electrodes, such as platinum or gold, can also be used but may be more expensive and less accessible. The carbon electrodes do not undergo any chemical changes during the process, but if they become damaged, they may decrease the efficiency of electrolysis.

Most metals easily dissolve in ionic form (unless they are noble metals - but these are expensive). Carbon can be oxidized to carbon dioxide, but this is a slow process, besides, product is a gas, which will easily leave the solution.
 

FAQ: Why are carbon electrodes neutral in electrolysis of water?

1. Why are carbon electrodes used in electrolysis of water?

Carbon electrodes are used in electrolysis of water because they are inert, meaning they do not react with the substances being electrolyzed. They are also inexpensive and readily available.

2. How do carbon electrodes remain neutral in electrolysis of water?

Carbon electrodes remain neutral because they do not participate in the chemical reactions taking place during electrolysis. They simply act as conductors for the electric current.

3. Can other types of electrodes be used in electrolysis of water?

Yes, other types of electrodes such as platinum or gold can also be used in electrolysis of water. However, these electrodes are more expensive and may not be as readily available as carbon electrodes.

4. What happens to the carbon electrodes during electrolysis of water?

The carbon electrodes do not undergo any chemical changes during electrolysis of water. They simply transfer the electric current to the water, causing the water molecules to break down into oxygen and hydrogen ions.

5. How do carbon electrodes affect the efficiency of electrolysis of water?

Carbon electrodes do not affect the efficiency of electrolysis of water as long as they are in good condition and able to conduct electricity effectively. However, if they become damaged or corroded, they may hinder the flow of electricity and decrease the efficiency of the process.
