Ammonium Chloride (NH₄Cl)
Chemical Formula: NH₄Cl
Molar Mass: 53.49 g/mol
Common Names: Sal ammoniac, nushadir salt
Appearance: White crystalline powder or granules
Odor: Odorless (but releases ammonia gas when heated)
Key Properties
- Solubility:
- Highly soluble in water (37 g/100 mL at 25°C).
- Slightly soluble in ethanol, insoluble in acetone/ether.
- pH in Solution: ~4.5–6 (weakly acidic due to hydrolysis):NH4++H2O⇌NH3+H3O+NH4++H2O⇌NH3+H3O+
- Sublimation: Decomposes on heating (>338°C) into NH₃ (g) and HCl (g).
- Hygroscopic: Absorbs moisture slowly from air.
Uses of Ammonium Chloride
1. Industrial Applications
- Dry Cell Batteries (Leclanché cells):
- Electrolyte in zinc-carbon batteries.
- Flux in Soldering & Metalworking:
- Cleans metal surfaces by removing oxide layers.
- Textile & Dyeing Industry:
- Fixative for dyes (e.g., in printing fabrics).
2. Agriculture & Animal Feed
- Nitrogen Source in Fertilizers:
- Provides NH₄⁺ for acidic soils (e.g., for rice crops).
- Yeast Nutrient:
- Used in baking and fermentation processes.
3. Laboratory & Chemical Synthesis
- Buffer Solutions:
- NH₄Cl/NH₃ buffers in analytical chemistry (pH ~9–10).
- Precipitating Agent:
- Isolates [AgCl] in qualitative analysis.
- Cooling Baths:
- Mixed with ice for sub-zero temperatures.
4. Medical & Pharmaceutical
- Expectorant in Cough Syrups:
- Thins mucus (now largely replaced by safer alternatives).
- Urinary Acidifier:
- Treats metabolic alkalosis (rare clinical use).
5. Food Additive (E510)
- Dough Conditioner:
- Used in licorice production (e.g., salty licorice).
Safety & Handling
- Irritant: Dust may irritate eyes, skin, and lungs.
- Toxicity:
- Harmful if ingested in large amounts (causes metabolic acidosis).
- Releases toxic HCl and NH₃ fumes when heated.
- Storage:
- Keep in airtight containers, away from moisture and bases.
- PPE:
- Gloves and goggles for handling powder.
Comparison with Sodium Chloride (NaCl)
| Property | NH₄Cl | NaCl |
|---|---|---|
| Taste | Salty-bitter | Pure salty |
| pH in Water | Acidic (~5) | Neutral (~7) |
| Thermal Stability | Decomposes on heating | Stable up to melting |
| Biological Role | Used in medicine | Essential electrolyte |
Synthesis & Production
- Industrial Method:
- Reaction of ammonia (NH₃) with hydrochloric acid (HCl):NH3+HCl→NH4ClNH3+HCl→NH4Cl
- Byproduct of Solvay Process:
- Obtained during sodium carbonate (Na₂CO₃) production.
