OriginSodium sulfate is a salt compound derived from sulfuric acid and sodium hydroxide or sodium chloride sources. It is produced through neutralization reactions or crystallization from natural mineral deposits and industrial byproducts.
Sodium Sulfate Anhydrous is the anhydrous, sodium salt form of sulfuric acid. Sodium sulfate anhydrous disassociates in water to provide sodium ions and sulfate ions. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. Sodium sulfate anhydrous is an electrolyte replenisher and is used in isosmotic solutions so that administration does not disturb normal electrolyte balance and does not lead to absorption or excretion of water and ions.
