Applications of Sodium Thiosulphate

1. Photography

• Acts as a "fixer" in the photographic process.
• Dissolves unexposed silver halide crystals, stabilizing photographic images.

2. Medicine

• Detoxification Agent:
  • Used to treat cyanide poisoning by converting cyanide into the less toxic thiocyanate, which is excreted by the body.
• Dermatology: Applied in the treatment of fungal infections and some skin conditions like pityriasis versicolor.

3. Water Treatment

• Dechlorination:
  • Neutralizes chlorine and chloramines in drinking water and aquariums.
  • Prevents harmful effects on aquatic life.

4. Chemical Industries

• Reducing agent in various chemical syntheses.
• Used in iodometric titrations due to its ability to react with iodine.

5. Gold Extraction

• Plays a role in the gold leaching process as part of the alternative lixiviants used in place of cyanide.

6. Textile and Paper Industries

• Used as a bleaching agent and in dyeing processes.
