What Is Sodium Thiosulfate Pentahydrate?

Sodium thiosulfate pentahydrate is a versatile chemical that takes the form of a white translucent crystal. It is soluble in water, but not in alcohol, and it can be absorbed by the air if the surroundings are sufficiently moist. The chemical has a number of different types of applications, such as cleaning, crystal growing and photography. This chemical is also used in the manufacture of certain patinas.

Sodium thiosulfate pentahydrate has a tetrahedral shape and is derived by replacing one of the oxygen atoms with a sulfur atom under certain circumstances. It is used in different industries for different purposes, including in manufacturing and as a means of dechlorinating certain small bodies of water such as ponds or even domestic aquariums.

Sodium thiosulfate pentahydrate is a fixing agent in photography, which means it can dissolve silver salts from negatives, and it is used as part of the photo developing process. When dissolved in a large amount of warm water, it can be used as a cleaner for removing Betadine or iodine spills. Additionally, because sodium thiosulfate pentahydrate can easily form monoclinic crystals, it is sometimes used to grow large crystals when used with certain crystal growing protocols and the correct substances.
