For chemists, engineers, and researchers, a thorough understanding of a chemical compound's properties is fundamental to its effective and safe utilization. NINGBO INNO PHARMCHEM CO.,LTD. delves into the chemical properties and stability of Ammonium Thiosulfate (CAS 7783-18-8), a compound vital to industries ranging from photography to agriculture.

Ammonium Thiosulfate, with the chemical formula (NH4)2S2O3, is an inorganic salt. In its pure form, it typically appears as a white, crystalline powder or solid. It is notable for being hygroscopic, meaning it readily absorbs moisture from the surrounding atmosphere. This characteristic necessitates careful storage in airtight containers to prevent caking and maintain accurate measurement. The compound's density is approximately 1.679 g/cm³, and it decomposes upon heating, with a decomposition point often cited around 180°C, releasing ammonia, sulfur oxides, and nitrogen oxides.

One of the most significant properties of Ammonium Thiosulfate is its high solubility in water, with a solubility of about 173 g/100 mL at 20°C. This high aqueous solubility is key to its widespread use in solutions for various applications. It is also slightly soluble in acetone but insoluble in ethanol and diethyl ether. Chemically, the thiosulfate ion (S2O3^2-) is a reducing agent and can react with oxidizers. The ammonium ion (NH4^+) provides ammoniacal nitrogen, a readily usable nutrient form for plants.

Regarding stability, while the solid form is susceptible to moisture absorption, properly stored solutions of ammonium thiosulfate are generally stable for extended periods. The compound is considered stable under recommended storage conditions. However, it is sensitive to heat and should be protected from direct sunlight and high temperatures. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its products are manufactured and packaged to maintain optimal stability and purity, making it a reliable choice for industrial clients. Customers seeking to buy ammonium thiosulfate can trust our commitment to quality.

The chemical behavior of ammonium thiosulfate is also important in its application. In photographic fixing baths, it readily forms soluble complexes with silver ions. In agriculture, the thiosulfate ion can be metabolized by soil microbes and plants, eventually converting to sulfate, providing sulfur for plant nutrition. Understanding these chemical reactions and properties allows users to maximize the effectiveness of ammonium thiosulfate in their specific applications. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-purity chemicals and supporting our clients with the technical knowledge needed for their successful implementation.
