In Down's Cell, the anode is made up of:
Correct answer: A. Graphite
- A. Graphite
- B. Copper
- C. Iron
- D. Silver
Explanation
In a Down's cell, which is an electrolytic cell used for the production of sodium metal through the electrolysis of molten sodium chloride (NaCl), the anode is made up of graphite.Graphite is an excellent material for the anode in this process due to its high melting point, chemical stability, and electrical conductivity. It can withstand the high temperatures and harsh conditions present during the electrolysis of molten sodium chloride.Option B) Copper, option C) Iron, and option D) Silver are not typically used as materials for the anode in a Down's cell. These materials may not possess the necessary properties to withstand the conditions and requirements of the electrolysis process.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
