In the extraction of sodium from fused sodium chloride, the anode is made of platinum because
- sodium is formed at the anode
- chlorine is formed at the anode
- sodium does not react with platinum
-
chlorine does not react with platinum
The correct answer is: D
Explanation
Because platinum is resistant to chlorine and water, hence in the electrolytic process, it doesn't react with any chemical and we get pure products.
