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

Explanation

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

### Step-by-Step Solution:

1. **Identify the reactants**: The main reactant in the Hall-Heroult process is aluminum oxide (Al₂O₃), which is often mixed with cryolite (Na₃AlF₆) and calcium fluoride (CaF₂) to enhance conductivity and lower the melting point.

2. **Write the balanced reaction**: In the Hall-Heroult process, aluminum oxide is reduced to aluminum metal at the cathode, while carbon (from the anode) is oxidized to carbon dioxide. The overall reaction can be summarized as follows:
- The reaction involves 2 moles of Al₂O₃ reacting with 3 moles of carbon (C).
