Introduction of Sodium sulfate decahydrate (Na₂SO₄·10H₂O), or Glauber's salt, is a hydrated crystalline compound. It forms colorless, translucent crystals, melting at 32°C as it dissolves in its own water. Primarily used in detergents (as a filler) and textiles (dye-leveling), it also serves in thermal energy storage systems due to reversible hydration-dehydration cycles. Historically a laxative, it’s now rare in medicine. Highly water-soluble, it effloresces in dry air, losing water to form anhydrous sodium sulfate. Low toxicity but may irritate eyes/skin. Its phase-change properties at 32°C make it valuable for solar heating or industrial heat management.

Application of Sodium Sulfate Decahydrate (Na₂SO₄·10H₂O), commonly known as Glauber's salt, is a hydrated crystalline form of sodium sulfate. Here's a concise overview:
Chemical Formula: Na₂SO₄·10H₂O (10 water molecules per formula unit).
Appearance: Colorless, translucent crystals.
Melting Point: ~32°C (89.6°F), where it dissolves in its own water of hydration.
1. Industrial:
Detergents & Textiles: Acts as a filler or processing aid in powdered detergents and dye-leveling agent.
Thermal Energy Storage: Stores/releases heat in solar heating systems due to reversible hydration-dehydration cycles.
2. Laboratory:
Mild drying agent (less common than anhydrous form).
3. Medical:
Historically used as an osmotic laxative (now largely replaced by modern alternatives).
Solubility: Highly soluble in water.
Stability: Effloresces (loses water) in dry air, forming anhydrous Na₂SO₄.
Low toxicity but may irritate eyes/skin.
Environmentally benign but excessive use can alter soil/water salinity.
Its reversible phase change at 32°C makes it useful in thermal applications, while its water content enables controlled hydration in industrial processes.
