Sodium sulfate decahydrate, famously known as Glauber's salt, is a fascinating chemical compound with a rich history and distinct properties that have influenced various fields, most notably medicine and industry. Discovered in the 17th century by German-Dutch apothecary Johann Rudolf Glauber, it was initially lauded for its medicinal properties, particularly as a potent laxative. This historical significance highlights the compound's early recognition for its physiological effects.

The chemical structure of sodium sulfate decahydrate (Na2SO4·10H2O) includes ten water molecules within its crystalline lattice. This hydrated form presents as colorless or white monoclinic crystals. Its solubility in water is notable, and it possesses a unique characteristic related to its melting point of approximately 32.38 °C. At this specific temperature, the decahydrate salt melts and releases its crystal water, existing in equilibrium with its anhydrous form and saturated solution. This property has historically been utilized for thermometer calibration.

While its medicinal use as a purgative was widespread, modern medical practices have largely adopted more targeted and less harsh alternatives. However, the underlying osmotic effect that Glauber's salt exerts on the gastrointestinal tract, drawing water into the intestines and stimulating peristalsis, remains a testament to its powerful physiological action. It is also known to act as an antidote for certain types of poisoning, such as barium salt poisoning, by forming insoluble barium sulfate in the digestive system.

Beyond its medical applications, the properties of sodium sulfate decahydrate, and by extension, the anhydrous form, are critical in industrial settings. Its ability to absorb moisture makes it a useful drying agent in laboratories for organic solvents. Its role as a filler in detergents and as an additive in papermaking and glass manufacturing further cements its industrial value.
