Known Chemical Reactions
Excellent 👍 — let’s move on in **periodic table order**.
Now we’re at **Sodium (Na, atomic number 11)**.
Unlike neon, sodium is **not found free in nature** (too reactive). It’s abundant in compounds, especially **sodium chloride (NaCl, common salt)**, and must be extracted by **reduction or electrolysis**.
Here are the **20 most common methods of extracting sodium**:

# **20 Most Common Methods of Extracting Sodium**
### **A. Industrial / Large-Scale Methods**
1. **Downs Cell Electrolysis of Molten NaCl** – The main modern process; molten NaCl with CaCl₂ (to lower melting point) is electrolyzed, yielding liquid sodium metal.
2. **Castner Process (Electrolysis of Molten NaOH)** – Historic method, replaced by the Downs cell for efficiency.
3. **Electrolysis of Molten Sodium Carbonate (Na₂CO₃)** – Alternative explored in early research.
4. **Electrolysis of Sodium Nitrate (NaNO₃)** – Sometimes investigated as a lab-scale route.
5. **Electrolysis with Fused Salt Mixtures (NaCl–KCl–CaCl₂)** – Reduces energy costs by lowering melting point.
6. **Diaphragm-Type Electrolysis Cells** – Variants of the Downs design, with barriers to reduce chlorine recombination.
---
### **B. Chemical Reduction Routes**
7. **Reduction of Na₂CO₃ with Carbon at High Temperature** – Ancient method (produced “soda” mixtures, not pure Na metal).
8. **Reduction of Na₂O with Aluminum or Magnesium** – Displacement reactions that yield sodium.
9. **Reduction of NaOH with Magnesium** – Early 19th century lab preparation.
10. **Reduction of NaCl with Calcium Carbide (CaC₂)** – Yields Na vapor and CaCl₂.
11. **Reduction of Sodium Compounds with Potassium Metal** – Used historically in labs, since potassium reduces Na salts.
12. **Reduction of Sodium Compounds with Barium or Calcium** – Thermochemical routes.

### **C. Vacuum & Thermal Methods**
13. **Vacuum Distillation of Sodium Amalgam** – Separates sodium from mercury (historic).
14. **Thermal Decomposition of Sodium Azide (NaN₃)** – Produces metallic sodium + nitrogen gas (lab-scale).
15. **Thermal Reduction of Na₂SO₄ with Carbon + Calcium Oxide** – Produces crude sodium vapors.
16. **Distillation of Sodium Vapor from Fused Salts** – Used in early experiments before electrolysis became dominant.

### **D. Specialized / Research Approaches**
17. **Electrolysis of Sodium Amalgam** – Sodium obtained from mercury cathode amalgams.
18. **Extraction from Sodium Vapor in High-Temperature Plasmas** – Research-level production.
19. **Laser-Induced Reduction of Sodium Salts** – Laboratory-scale experimental approach.
20. **Electrochemical Extraction in Ionic Liquids** – A safer modern research method that avoids molten salt hazards.

✅ **Summary:**
* **Main industrial method today:** Downs cell electrolysis of molten NaCl + CaCl₂.
* **Historic methods:** Castner process (molten NaOH electrolysis), chemical reductions (with Mg, Al, etc.).
* **Lab/research methods:** Thermal decomposition (NaN₃), vacuum distillation, ionic liquids.
* **Natural occurrence:** Sodium is abundant (≈2.6% of Earth’s crust), but always as salts (NaCl, Na₂CO₃, Na₂SO₄).
