Graphite is used for making electrodes, why?

Step 1 Understanding the concept: Allotropes are different structural forms of the same element and can show quite different physical properties but the same chemical behaviors. Example: Diamond and Graphite are the two important allotrophs of carbon.

Step 2 Explanation:

• Electrolysis uses graphite rods as electrodes because graphite's structure makes it an excellent conductor.
• Electricity can pass through graphite rapidly due to a large number of delocalized electrons.
• Graphite is very simple to form into a rod shape, as well as being a cost-effective and durable material.
• Because of its outstanding conductive qualities, high melting point (which allows it to be utilized in a wide range of electrolysis processes), low cost, and toughness, graphite is a good choice for electrolysis electrodes.
• Positively charged ions (metals and hydrogen) can get electrons from the negatively charged electrode due to graphite. Negatively charged ions, on the other hand, lose electrons (oxidation).
