Answer Details
The anode in the extraction of sodium from fused sodium chloride is made of platinum because sodium does not react with platinum. In this process, an electric current is passed through a molten mixture of sodium chloride to separate the sodium and chlorine ions. The anode attracts the negatively charged chloride ions, while the cathode attracts the positively charged sodium ions. The platinum anode does not react with the sodium ions, allowing for their separation from the chloride ions and the successful extraction of sodium.
