However, … WebIn the case of palladium, nitrate ions in the solution oxidised the metal. A chloropalladate (II) complex between the oxidised metal and chloride anions formed and was stable at the low pH. In a matter of hours, the palladium had fully dissolved in solution, and the palladium metal was then recovered via reductive precipitation using ascorbic acid.
