2017-3-27  Extraction of Copper - Purification by Electrolysis. High purity copper is needed to make electrical wires. The anode is a block of impure copper. The cathode is a thin piece of pure copper. The electrolyte is copper sulfate. When electricity is passed through the cell copper is dissolved at the anode by oxidation and Cu 2+ ions go into solution.

The Purification of Copper by Electrolysis involving Oxidation and Reduction. Electrolysis - UW-Madison Chemistry. Because impurities can dramatically decrease the conductivity of copper wires, impure copper must be purified One method of purifying copper is by electrolysis. purification of copper by electrolysis metal extraction ,

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.
