About Sodium Sulfate Anhydrous, ACS Grade (Fine Granular)

Sodium Sulfate Anhydrous is an inorganic salt, fine granular form. It readily dissolves in water and dissociates into sodium and sulfate ions. The sodium ion is the most abundant cation in extracellular fluid and is used extensively in the treatment of fluid/electrolyte imbalance. 

In its anhydrous form, sodium sulfate is a versatile compound used in detergent manufacturing, the textile industry, paper production, chemical manufacturing, glassmaking, and more. It's valued for its ability to act as a drying agent, desiccant, and for its role in various chemical reactions. 

ACS grade chemicals are of high purity and are suitable for laboratory use, particularly in analytical chemistry, where precise measurements and consistent performance are crucial.
