Sodium Thiosulfate Pentahydrate

Sodium Thiosulfate Pentahydrate ACS is a colorless, crystalline solid. This form of sodium thiosulfate is hydrated, with the chemical formula Na2S2O3 · 5H2O. It contains sodium ions (Na+), thiosulfate ions (S2O3^2-), and five water molecules (H2O) per formula unit. Sodium Thiosulfate Pentahydrate ACS is highly soluble in water and has a tendency to absorb moisture from the air, resulting in the pentahydrate form. The ACS grade certification ensures that this compound meets the purity standards set by the American Chemical Society, guaranteeing quality and consistency in laboratory applications. This reagent is odorless, and suitable for use in large-scale operations.
