    The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agentОнлайн-запрос

  • Is a gold electrode supposed to corrode during electrolysis?

    23/10/2017· Gold is soft so might be easy to erode or roughen and this would give it a dull non-reflective appearance. The fact that you seem able to reverse the degradation by remelting the surface would seem to support this scenario. I noticed this with my electrolysis experiments in junior high.

  • Electrolytic Cells: Electrolysis | SparkNotes

    To make the electrolysis of water occur, one must apply an external potential (usually from a battery of some sort) of greater than or equal to 1.23 V. In practice, however, it is necessary to use a slightly larger voltage to get the electrolysis to occur on a reasonable time scale. Pure water is impractical to use in this process because it is an electrical insulator. That problem is
