Overview of Sodium Thiosulphate Anhydrous

Sodium Thiosulphate Anhydrous, an inorganic industrial sodium that is extensively employed in the manufacturing of products where it is a moisture-free mixture and controlled sulphur chemistry and a steady reducing behaviour are essential. It is sold in the form of a white powder and is favoured in industrial applications that require precise dosage, a long shelf life, and stable chemical performance, without the addition of water.

The formula for sodium thiosulfate anhydrous is Na₂S₂O₃, and its anhydrous form makes it suitable for moisture-sensitive industrial operations such as chemical processing, water treatment, photographic processing, and specialty industrial applications.


Applications of Sodium Thiosulphate Anhydrous

Water Treatment & Dechlorination

Sodium Thiosulphate Anhydrous can be extensively utilized in water treatment for neutralization and dechlorination of oxidizing agents that remain. It is a safe and controlled method of reduction, as well as a secure removal of the treated water within industries with a utility system. It is frequently used in conjunction with sodium metabisulfite to control the process of eliminating oxidants and chlorine.

Chemical Manufacturing & Industrial Processing

Sodium Thiosulphate Anhydrous is used in chemical manufacturing where controlled sulphur-based reduction reactions are required. Its moisture-free nature supports predictable reaction behaviour and consistent batch quality. It may be evaluated with Sodium Sulphite depending on the reduction strength requirements.

Photographic & Imaging Processing

Sodium Thiosulphate Anhydrous is traditionally used in photographic and imaging applications as a fixing agent, where it dissolves unreacted silver salts and stabilises images. It is often handled with Silver Nitrate in photographic chemical systems.

Specialty Industrial Applications

Sodium Thiosulphate Anhydrous can also be employed in special industrial applications like metal treatment, laboratory processing and controlled sulphur chemical systems where stability and precise solubility are needed.


Safety & Handling Guidelines

  • Store in a cool, dry, and well-ventilated area
