Sodium sulfate 1% solution, consisting of 1000 ml distilled aqua/VE water and 10.10 g anhydrous sodium sulfate, is widely used in medical diagnostics, histology and scientific laboratories. The solution is an important component of staining kits such as the SAB (Sulfated Alcian Blue) kit. In histology, it is used to selectively stain acidic glycosaminoglycans found in extracellular matrix components such as cartilage and connective tissue.

The chemical formula of sodium sulfate is Na2SO4. In solution, it dissociates into sodium ions (Na+) and sulfate ions (SO4²-). The chemical properties of the solution, such as hydration and interactions between the ions and water molecules, allow it to bind selectively to acidic glycosaminoglycans.

The chemical reactions that occur during the use of sodium sulfate 1% solution involve the interaction of Alcian Blue, a basic dye, with acidic glycosaminoglycans. The presence of sodium sulfate promotes selective binding of the dye to the acidic glycosaminoglycans by affecting the electrostatic interactions between the charged groups of the dye and the acidic glycosaminoglycans.

Possible outcomes of using this solution include improved visualization and identification of acidic glycosaminoglycans in tissue samples, which may lead to more accurate diagnosis and analysis of tissue structures. In summary, sodium sulfate 1% solution is essential for selective staining of acid glycosaminoglycans.
