Explain the electrometallurgical process for the extration of potassium using fused potassium chloride

Answer»

Solution :ELECTROLYTE : Fused potassium chloride
Cathode : IRON
Anode: Graphite (INERT anode)
Dissociation of electroyte : `KCl RARR K^(+) + CL^(-)`
Reactions at the cathode : `K^(+) + e^(-) rarr K`
Reactions at the anode: `[Cl^(-) - e^(-) rarr Cl^(-)] xx 2`
`Cl + Cl rarr Cl_(2)`
