Sodium Thiosulphate: A Multipurpose Chemical For Labs, Industry, And Medicine

Sodium Thiosulphate (Na₂S₂O₃), also known historically as hypo, is a versatile inorganic compound used across a wide range of industries and laboratory environments. Appearing as colorless, crystalline granules or powder, it is highly soluble in water and known for its role in neutralizing chlorine, fixing photographic images, and reacting with iodine.

At Amaris Chemical Solutions, we supply Sodium Thiosulphate Extra Pure for laboratory and industrial use, adhering to stringent quality controls. Our product is available in multiple grades and packaging sizes to meet varying application needs—from analytical labs to industrial-scale water treatment.

🏭 Primary Applications of Sodium Thiosulphate

1. Water Treatment

• Acts as an effective dechlorinating agent to remove residual chlorine from drinking water, wastewater, and aquariums.
  
• Neutralizes hypochlorite solutions used in disinfection processes.
  

2. Photographic Processing

• Historically used as a fixer to dissolve unreacted silver halides in black-and-white photography.
  
• Still employed in certain analog and archival photographic applications.
  

3. Analytical Chemistry

• Used in iodometric titrations to determine concentrations of oxidizing agents (e.g., chlorine, iodine).
  
• Reacts quantitatively with iodine, making it essential in redox analysis.
  

4. Gold and Silver Extraction

• Acts as a non-cyanide leaching agent in the extraction of precious metals.
  
• An eco-friendlier alternative to sodium cyanide in mining.
  

5. Medical and Pharmaceutical

• Used as an antidote for cyanide poisoning, often administered alongside sodium nitrite.
  
• Investigated for potential treatments in calciphylaxis and other mineral imbalance disorders.
  

6. Textile and Paper Industries

• Used to neutralize bleaching agents and remove residual halogens after textile or pulp processing.
