From the given impurities in a sample of copper, which of the metals will be oxidized and dissolved in solution and also which will be unaffected and simply forms sludge at the bottom of the cell has to be explained. Concept introduction: There are three methods commonly used to separate metals form its ores. They are distillation, electrolysis , and zone refining. All these methods are base on reduction process. In our problem we discuss about electrolysis. Electrolysis: The reduction of metallic compounds to obtain pure metals using current is said to be electrolysis. In the process of electrolysis of copper ore, the more electropositive metals are eliminated by an electrolysis. In this method the impure copper acts as the anode and pre copper acts as the anode through a sulfuric acid solution medium containing Cu 2+ ions. Copper anode dissolves and these metals are fall down to the bottom of the cell. Then, the net result of this process is exchange of copper form the anode to the cathode.
