Sodium Thiosulphate Pentahydrate

Product Description

Sodium Thiosulphate Pentahydrate is a high-quality industrial chemical that is widely used in various applications. With a purity of 97%, this powder is a valuable source of thiosulfate ions that are essential for many chemical reactions. Although it is poisonous, it is safe to store at room temperature, making it convenient for industrial use. This chemical has a pH level of 3.0, which makes it an excellent buffering agent. It is also used in photography and as a dechlorinating agent in water treatment plants. Its physical form is a powder, which makes it convenient for handling during manufacturing processes.

Sodium thiosulfate) is an inorganic compound with the formula Na2S2O3Â(H2O)x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water.

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."

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.
