  Purification of Copper via Electrolysis - Chemistry Guru

  2  · Electrolysis can be used to purify impure copper that contains other metals such as silver, gold, iron and zinc. The purity of copper can be increased from 99% in impure copper to almost 99.99% in pure copper. This purification process via electrolysis is important as slight amounts of impurity in copper will reduce its electrical conductivity. 1.

  Chemistry of Copper - Chemistry LibreTexts

  Copper (I) chemistry is limited by a reaction which occurs involving simple copper (I) ions in solution. This is a good example of disproportionation - a reaction in which something oxidises and reduces itself. Copper (I) ions in solution disproportionate to give copper (II) ions and a precipitate of copper.
