Product Description

1. Basic Information
   • Chemical Formula: Na₂S₂O₃.5H₂O/Na₂S₂O₃
   • Physical Properties: It is typically a colorless or white crystalline solid. It is odorless when pure, but may have a sulfur - like odor if impure. It is highly soluble in water.
2. Chemical Properties
   • Reducing Property: Sodium thiosulfide is a powerful reducing agent. It can react with oxidizing agents in many chemical reactions. For example, it reacts with iodine to form sodium iodide and sodium tetrathionate, which is the basis for its use in iodometric titrations.
   • Complex - forming Property: It has the ability to form complexes with certain metal ions. This property is useful in various industrial and analytical processes.

Application

 

• Photography Industry: It is widely used as a fixer in photography. It dissolves the unexposed silver halides on photographic film or paper, preventing further reaction with light and making the image stable and permanent.

Water Treatment

 

In water treatment, it neutralizes chlo rine. By reacting with chlo rine, it makes water safe for aquatic life, like in aquariums.

• Textile Industry: In the textile industry, it is used for bleaching and desulfurization processes. It can remove excess bleach and sulfur - containing impurities from fabrics, improving the quality of the textile products.

• Chemical Analysis: In analytical chemistry, it is commonly used in iodometric and iodimetric titrations to determine the concentration of oxidizing or reducing substances. It provides a convenient and accurate method for quantitative analysis.
