Refining of Palladium and making its salt

Feb 19, 2021· 1) Use Silver. Silver is above copper, but below palladium, on the electromotive series, so adding silver to the copper/palladium solution will precipitate the palladium and leave the copper in solution. Remove the precipitated palladium and add sodium chloride to the remaining copper solution, and the silver will be recovered as silver chloride.
