Practical electrolysis

2017/6/16Electrolysis is at the heart of aluminium production, copper purification, and the production of sodium hydroxide and chlorine. Students will appreciate the relevance of these processes when they find out the annual world production of these chemicals is measured in megatonnes (table 1, below).

Understand Electrolysis Worksheet

Purifying copper Electrolysis is also used to purify metals, such as copper. Copper is extracted as an ore (compounds of copper with other elements) and is purified with this method. The anode is the impure copper; it dissolves into the electrolyte, and pure.

Electrolytic Processes

Purifying copper Copper can be purified by electrolysis.Electricity is passed through solutions containing copper compounds, such as copper sulfate. In this process, the anode would be made from impure copper and the cathode made from pure copper. Copper ions are positive (Cu⁺), so move to the negative electrode (cathode).(cathode).

Electrolysis

Because impurities can dramatically decrease the conductivity of copper wires, impure copper must be purified. One method of purifying copper is by electrolysis. W hen a strip of impure metallic copper is used as the anode in the electrolysis of an aqueous preparation of copper(II) sulfate, copper is
