What Is Electrolytic Copper? Sciencing

Apr 24, 2017 · The electrolyte solution consists of copper sulfate, according to Science Clarified. An electric current causes copper ions from the anodes to enter the solution and become deposited onto the hode. Impurities either fall away and form sludge or stay in solution. The hode gets bigger as pure copper forms on it, while the anode shrinks.

The purifiion of metals by electrolysis. It is commonly applied to copper. A large piece of impure copper is used as the anode with a thin strip of pure copper as the hode. Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode: Cu → Cu2++2e, and is deposited at the hode. The net result is transfer of pure copper from anode to hode.
