Product Description
Product Name: Sodium Thiosulfate
Chemical Formula: Na2S2O3
Common Names: Hypo, Thiosulfate
Sodium thiosulfate usually appears as colorless transparent crystals or white crystalline powder, soluble in water and hygroscopic. Its molecular formula is NA2S203.5H2O, with a density of 1.667g/cm ³ (anhydrous) or 1.729g/cm ³ (pentahydrate salt). In the aqueous solution of baking soda, there are usually five crystal waters (NA2S203.5H2O), which will weather and lose their crystal waters in dry air above 33 ºC

Application
-
Photography and Film Processing
-
Fixing Agent: Sodium Thiosulfate is a key component in photographic fixing solutions. It reacts with unexposed silver halides to form soluble complexes, thereby stabilizing the image and preventing further development.
-
Film Processing: Used in the final stages of film development to remove undeveloped silver halides and ensure a clear, stable image.
-
Water Treatment
Heavy Metal Removal: Acts as a reducing agent to remove heavy metals such as copper and lead from water, making it suitable for industrial effluent treatment.
