In this episode, we discuss using electrolysis to extract reactive metals.

Electrolysis is a method employed to extract reactive metals, such as aluminium, from their molten ores because these metals are more reactive than carbon. 

This process involves passing an electric current through the molten compound, causing the metal ions to be reduced at the cathode, forming the pure metal. 

At the anode, oxygen typically forms and reacts with the carbon electrode, producing carbon dioxide. 

While effective for obtaining highly reactive metals, electrolysis is a costly procedure due to the substantial energy required to melt the ore and generate the necessary electrical current. 

Therefore, although crucial for specific metal extractions, the energy demands represent a significant drawback of this technique.
