About Sodium Thiosulfate Pentahydrate, Lab Grade
Sodium Thiosulfate Pentahydrate, also known as Disodium Sulfurothioate Pentahydrate, and
Sodium Hyposulfite Pentahydrate is a hydrate of Sodium Thiosulfate with 5 mol eq. of Water.
having the chemical formula H10Na2O8S2 or Na2S2O3-5H2O. It appears as colorless to white
hygroscopic crystals, chunks, or crystalline powder with no odor. It is sparingly soluble in Water
and insoluble in Alcohol at ambient conditions. When heated to around 300 o C, it undergoes
decomposition emitting highly toxic fumes of Disodium Oxide and Sulfur Oxides. Commercially,
it is produced by reacting by-product liquid of Sodium Sulfide synthesis with Sulfur Dioxide.
Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade
chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as
the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity. In the United
States of America (USA), Lab Alley is selling its high-quality Sodium Thiosulfate, Anhydrous,Lab Grade online at laballey.com. Due to its high purity, this Lab Alley product is highly
recommended for labs and commercial applications.
