Description
This is
Sodium thiosulfate, Na2S2O23
Inorganic substances with the chemical composition of Na2S2O3*5H2O include sodium thiosulfate, pentahydrate and potassium thiosulfate pentahydrate.
This sodium thiosulfate, Na2S2O3, is a colorless monoclinic Crystal with an odorless taste. It has a specific gravity of 1.729 when heated to 100°C. Five crystal water molecules are then lost.
Water-soluble, but insoluble in alcohol. Strong reducibility.
In dry, above-33F air, sodium thiosulfate (Na2S2O3) is easy to weather and in humid conditions it deliquesces.
