A scrap metal dealer gets a huge consignment of crude metallic Lead. For a profitable deal he needs to refine the metal using electrolysis. Which one of the following is a good choice for an electrolyte?
PbSiF6
PbSiF6 is the preferred choice of electrolyte. Sometimes a combination of PbSiF6 and H2SiF6 is used in the electrolytic refining process. (Impure or crude lead is the anode while a pure lead cathode is used).
