Meta Description: This comprehensive guide provides a detailed look at Anhydrous Sodium Sulfate SDS, covering its properties, hazards, handling, and safety precautions. Learn about its uses in various industries and how to ensure safe handling and storage. Understand the crucial information outlined in the Safety Data Sheet (SDS).

Understanding Anhydrous Sodium Sulfate

Anhydrous sodium sulfate (Na₂SO₄), also known as sodium sulfate anhydrous, is an inorganic compound found naturally as the mineral thenardite. It's a white, crystalline powder readily soluble in water. Its anhydrous form means it's free from water molecules, a key characteristic influencing its applications. This makes it ideal for various industrial processes where water content needs to be controlled.

Key Properties of Anhydrous Sodium Sulfate:

Chemical Formula: Na₂SO₄
Molar Mass: 142.04 g/mol
Appearance: White crystalline powder
Solubility: Highly soluble in water
Melting Point: 884 °C (1623 °F)
Density: 2.66 g/cm³
