Graphite anodes are used in Down's cell for the electrolysis of molten sodium chloride due to their excellent conductivity and resistance to oxidation at high temperatures. The graphite's stability allows it to withstand the harsh conditions within the cell, where temperatures can exceed 600°C. Additionally, graphite helps in minimizing the formation of side products, ensuring efficient sodium production. Its cost-effectiveness and availability further contribute to its use in this industrial process.

Why you use iron cathode and graphite anode in downs cell?
In the Downs cell, iron is used as the cathode because it effectively reduces sodium ions to sodium metal, which is essential for the production of sodium. Graphite is chosen for the anode due to its excellent electrical conductivity and resistance to oxidation at high temperatures, allowing it to withstand the harsh conditions of the electrolysis process. Together, these materials facilitate the efficient and effective electrochemical reactions required for sodium production.
Is the electrode the metal or graphite rod in an electric cell?
Tt depends on the metal which is the cathode and which is the anode. However, in most cases, graphite is the cathode and the metal is the anode. the strictly correct answer is that BOTH the metal and the graphite rod are electrodes. You must have two electrodes minimum to create a cell.
What is role of graphite rod in electrometallurgy of Al?
In the electrometallurgy of aluminium, a fused mixture of purified alumina (Al 2 O 3 ), cryolite (Na 3 AlF 6 ) and fluorspar (CaF 2 ) is electrolysed. In this electrolysis, graphite is used as the anode and graphite-lined iron is used as the cathode. During the electrolysis, Al is liberated at the cathode, while CO and CO 2 are liberated at the anode, according to the following equation. If a metal is used instead of graphite as the anode, then O 2 will be liberated. This will not only oxidise the metal of the electrode, but also convert some of the Al liberated at the cathode back into Al 2 O 3 . Hence, graphite is used for preventing the formation of O 2 at the anode. Moreover, graphite is cheaper than other metals.
What material is used to make an anode?
The two most common materials used to make anodes are graphite and metals such as zinc, aluminum, or magnesium. Graphite anodes are often used in applications where high levels of electrical conductivity and chemical resistance are required, while metal anodes are typically used in sacrificial anode systems to protect steel structures from corrosion.
Why is graphite used as an electroed in dry cells?
Dry cell graphite electrode when treated with permanganate can be used as a hydrogen ion sensor. where activated dry cell graphite electrode seem to be suitable as potentiometric indicator electrodes. :)

Difference Downs cell and nelson cell are electrolytic cell between Daniel cell and fuel cell r galvanic or voltaic cell?
In Nelson's cell, an aqueous solution of concentrated NaCl is used for the industrial production of NaOH, while in Down's cell fused or molten NaCl is used for obtaining sodium metalIn Nelson's cell, three main chemicals are obtained as products that are Hydrogen gas, Chlorine gas and NaOH whereas in down's cell chlorine gas and sodium metal is produced as a product.In Down's cell, graphite is used as anode and iron is used as cathode. But, in Nelson's cell perforated steels is made cathode and grapite as anode.
What parts of a battery are used by two different types of metals?
The anode and the cathode are the metal components that are in contact with the electrolyte in a battery.
Which elementis used as graphite in a battery?
The element used as graphite in a battery is carbon. Graphite is a form of carbon that is commonly used as the anode material in lithium-ion batteries due to its conductivity and ability to intercalate lithium ions during charging and discharging processes.
Why are the electrodes used in electrolytic processes such as in the Downs cell and in the Hall-Heroult process always made of inert substances such as graphite or platinum.?
because they are good conductors of electricity and do not react with the electrolytes

Can you use lead as an anode in electrolysis?
Lead can be used as an anode in electrolysis, but it may not be the most optimal choice due to its tendency to corrode and form lead oxide during the electrolysis process. This can affect the efficiency and longevity of the anode. Using materials like platinum or graphite for the anode may be more suitable for certain electrolysis applications.
What minerals are in a car battery anode?
Common minerals found in a car battery anode include lead dioxide and lead sulfate. Lead dioxide is typically used in the positive plate of the anode, while lead sulfate forms on the negative plate during the discharge process.
