Product Parameters

Soda Ash (Sodium Carbonate) - Detailed Information
1. Chemical Properties  
Chemical Formula: Na2CO3  
Molecular Weight: 105.99 g/mol  
Appearance: White, odorless, crystalline powder or granules.  
Solubility: Highly soluble in water (22 g/100 mL at 20°C), insoluble in organic solvents.  
-pH: ~11 (strong alkaline solution when dissolved).  
-Melting Point: 851°C (1,564°F).  
- Density: 2.54 g/cm³ (anhydrous).  

2. Forms of Soda Ash 
Anhydrous Sodium Carbonate (Na2CO): Dry powder, most common industrial form.  
Monohydrate (Na2CO3·H2O): Crystalline form with one water molecule.  
Decahydrate (Na2CO3·10H2O, "Washing Soda")**: Transparent crystals, efflorescent (loses water in air).  

3. Production Methods  
Solvay Process (Dominant Method):  
  - Reactions:  
    - NaCl + NH3 + CO2 + H2O → NaHCO3 + NH4Cl  
    - 2NaHCO3 → Na2CO3 + CO2 + H2O (heated)  
  - Byproducts: Calcium chloride (CaCl2).  
Trona Ore Mining: Naturally occurring mineral (e.g., in Wyoming, USA; Turkey).  
  - Crushed, heated, and refined to produce soda ash.  
Leblanc Process (Historical): Obsolete due to environmental concerns.  

4. Key Applications
Glass Manufacturing (50% of global use): Lowers melting point of silica (key for flat and container glass).  
Detergents & Soaps: Water softener and pH regulator.  
Chemicals: Precursor for sodium bicarbonate, sodium silicate, and other compounds.  
Metallurgy: Flux in smelting, alumina production (Bayer process).  
Water Treatment: Neutralizes acidic wastewater.  
Food Industry: Food additive (E500, pH control in noodles, pretzels).  

5. Safety & Handling
Hazards:  
  - Skin/Eye Irritant (alkaline burns).  
  - Inhalation risk (dust causes respiratory irritation).  
Protection: Gloves, goggles, ventilation.  
Storage: Dry, sealed containers (hygroscopic).  

6. Environmental Impact 
Carbon Footprint: Solvay process emits CO2; Trona mining is more eco-friendly.  
Alternatives: Recycled glass reduces demand, but limited substitutes exist for high-purity needs.  

7. Related Compounds  
Sodium Bicarbonate (NaHCO3, Baking Soda): Milder base, derived from soda ash.  
 (NaOH): Produced via electrolysis of NaCl, not interchangeable.
