Question

What is a procedural difficulty when electrolyzing a molten salt?

Answer 1

There are many procedural difficulties in electrolyzing a molten salt which are following:

1. The composition of anion of the molten salt solvent
2. The composition of cation of the molten salt solvent
3. Solute concentration
4. Maintain temperature of the cell
5. Maintain Potential of cathode
6. Maintain current density of cathode
7. the corrosion of cell and electrodes
8. Sometimes the hydrolysis of many hygroscopic salts occurs.
9. Sometime compounds are highly volatile, or insoluble cluster-type compounds that rivert intermediate valency state compounds.
10. The total energy and economic process is costly.
