Sodium Thiosulfate Pentahydrate (CAS 10102-17-7) is a compound whose utility is deeply rooted in its distinct chemical properties and production pathways. This white crystalline powder, with a purity assay of 98%, serves numerous critical functions across various industries. Understanding its chemistry is key to appreciating its value, and sourcing it from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive a product that meets rigorous standards.

At its core, Sodium Thiosulfate Pentahydrate is an inorganic salt. The thiosulfate ion (S₂O₃²⁻) is characterized by a sulfur atom bonded to three oxygen atoms and another sulfur atom, giving it unique reactivity. This structure allows it to act as a potent reducing agent and a ligand capable of forming complexes with metal ions. These properties are fundamental to its diverse applications.

One of its most notable chemical reactions is its role as a reducing agent. It readily reacts with oxidizing agents, a property exploited in applications like water treatment to neutralize chlorine and in analytical chemistry for titrations. For instance, its reaction with iodine is a cornerstone of iodometry, where it quantitatively reduces iodine to iodide, enabling the determination of unknown concentrations of oxidizing substances.

Production methods for Sodium Thiosulfate Pentahydrate typically involve the oxidation of sodium sulfite with sulfur or the reaction of sodium hydroxide with sulfur. Industrially, it can also be derived from waste streams in sulfur dye manufacturing. The process aims to yield a high-purity product, ensuring its efficacy in sensitive applications. For industries that rely on precise chemical inputs, such as the pharmaceutical or electronics sectors, understanding the production process and sourcing from a reputable sodium thiosulfate pentahydrate manufacturer in China is crucial.

Beyond its reducing capabilities, Sodium Thiosulfate Pentahydrate is also recognized for its ability to form stable complexes with various metal ions, including silver and gold. This chelating property is leveraged in photographic processing, where it dissolves silver halides, and in mining for gold extraction. Its medical application as a cyanide antidote also stems from its ability to chelate and detoxify cyanide ions.
