Sodium Sulfate Anhydrous

Sodium Sulfate Anhydrous, with the chemical formula Na₂SO₄, is the dehydrated sodium salt of sulfuric acid, appearing as a white, crystalline powder or granules. Unlike its hydrated form (Glauber's Salt, Na₂SO₄·10H₂O), the anhydrous version is free of water molecules, making it highly stable and hygroscopic only under conditions of very high humidity. This compound is valued for its chemical inertness, high solubility in water, and low cost, serving as a fundamental processing aid, filler, and additive in a remarkably diverse range of industrial applications, from detergents to glass manufacturing.
