The Extraction of Copper - Chemistry LibreTexts

Any metal in the impure anode which is below copper in the electrochemical series (reactivity series) does not go into solution as ions. It stays as a metal and falls to the bottom of the cell as an "anode sludge" together with any unreactive material left over from the ore. The anode sludge will contain valuable metals such as silver and gold.

Electrochemical Series | Chemistry Assignment

The metals which occupy higher position in electrochemical series have lower reduction potentials. This indicates that ions of such metals will not be reduced to metals easily. On the contrary, such metals would be easily oxidized to their ions by losing electrons.

Electrochemical Series | Explanation Applications & Table

Oct 22, 2019 · Electrochemical series is also helpful in determining the stability of oxides form by the metals. The metals which are more electropositive in nature form more stable oxides. While the stability of the metal oxides decreases from top to bottom which means that metals with positive reduction potential form less stable oxides than metals which .
