Physical and Chemical Properties:
Sodium thiosulfate (sodium thiosulphate) is an inorganic compound  Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water. 

Application:
 

1. In photography, sodium thiosulfate is known as a fixer, sometimes still called 'hypo' from the original chemical name, hyposulphite of soda.It functions to dissolve silver halides, e.g., AgBr, components of photographic emulsions. It is used for both film and photographic paper processing. Ammonium thiosulfate is typically preferred to sodium thiosulfate for this application.

 

1. It is used to dechlorinate tap water including lowering chlorine levels for use in aquariums, swimming pools, and spas (e.g., following superchlorination) and within water treatment plants to treat settled backwash water prior to release into rivers.The reduction reaction is analogous to the iodine reduction reaction.

 

1. In pH testing of bleach substances, sodium thiosulfate neutralizes the color-removing effects of bleach and allows one to test the pH of bleach solutions with liquid indicators.
2.  

Other uses include topical treatment of ringworm and tinea versicolor, and treating some side effects of hemodialysis and chemotherapy.

f.  Sodium thiosulfate is used predominantly in dyeing. It converts some dyes to their soluble colorless "leuco" forms. It is also used to bleach "wool, cotton, silk, ...soaps, glues, clay, sand, bauxite, and... edible oils, edible fats, and gelatin.


Storage:
It shall be stored in dry, dark places and should be sealed to prevent moisture absorption and direct sunlight.
