Sodium sulfate decahydrate, known chemically as Na₂SO₄·10H₂O and historically as Glauber's Salt, is a compound whose industrial prowess stems directly from its chemical structure and behavior. Its fundamental role in various manufacturing sectors is a testament to its well-understood chemical properties.

At its core, sodium sulfate decahydrate is an ionic compound. When dissolved in water, it dissociates into sodium ions (Na⁺) and sulfate ions (SO₄²⁻). This high solubility in water is a key factor in its applications, allowing it to easily integrate into aqueous systems used in textile dyeing and detergent formulations. The neutrality of its aqueous solution, with a pH typically around 7, also means it doesn't drastically alter the pH of processes, making it a stable additive.

The crystalline structure of sodium sulfate decahydrate, featuring ten water molecules per formula unit, influences its physical properties, including its melting point. This specific hydration state is crucial for its use in thermal energy storage, although the primary industrial applications focus on its chemical reactivity and physical presence.

In textile dyeing, the sulfate ions contribute to the ionic strength of the dye bath. This increased ionic strength helps to neutralize the negative charges on textile fibers, allowing the dye molecules to approach and bind more effectively. This is the chemical basis for its role as a leveling agent, promoting uniform dye absorption and thus, consistent color throughout the fabric.

In glass manufacturing, sodium sulfate acts as a fluxing agent. While not a chemical reaction in the traditional sense, its presence in molten glass lowers the overall melting temperature of the silica, making the glass easier to form and manipulate. This physical-chemical interaction streamlines the glass production process.
