purifying copper by electrolysis

  • Purification of Copper - Animated Science

    Copper can be purified by electrolysis. The impure copper is made the anode (+) and a thin piece of pure copper is made the cathode (−). The electrolyte contains copper ions (e.g. copper sulfate solution). The copper atoms at the anode change into copper ions and enter the solution.

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

     · Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper cathode, 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 99.95 % by electrolytic refining in a cell similar to that shown below. A thin sheet of high-purity Cu serves as the cathode.
