Write the equation of the net reaction taking place in Hall Heroult electrolytic method for the collection of aluminium ?

Explanation

To derive the net reaction taking place in the Hall-Héroult electrolytic method for the collection of aluminum, we can follow these steps:

### Step 1: Understand the Process
The Hall-Héroult process is an industrial method for extracting aluminum from its ore, bauxite. The key component used in this process is aluminum oxide (Al₂O₃), which is dissolved in molten cryolite (Na₃AlF₆).

### Step 2: Write the Reaction for Electrolysis
During the electrolysis, aluminum ions are reduced at the cathode, and oxygen is oxidized at the anode. The overall reaction can be summarized as follows:
