     · Extraction and purifiion of copper. Copper is less reactive than carbon, so it can be extracted from its ores by heating it with carbon. For example, copper is formed if copper oxide is heated strongly with charcoal which is mostly carbon: copper oxide + carbon → copper + carbon dioxide. Copper is purified by electrolysis.

    4. The electrolysis of copper(II) sulfate solution. The electrolyte copper(II) sulfate, provides a high concentration of copper(II) ions Cu 2+ and sulfate ions SO 4 2– to carry the current during the electrolysis process. There are tiny concentrations of hydrogen ions H + and hydroxide ions (OH –) from the selfionisation of water itself, but these can be ignored in this experiment.

  • How can electrolysis be used to purify copper? | Socratic

     · Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper hode, leaving the impurities behind. Unrefined copper is about 99 % pure. It contains traces of metals such as Fe, Zn, Ag, Au, and Pt. The purity can be increased to % by electrolytic refining in a cell similar to that shown below. A thin sheet of highpurity Cu serves as the hode.
