Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na2S2O3.xH2O. Typically it is available as the white or colorless pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water. It is also often called sodium hyposulfite or hypo.
Sodium diacetate is a compound with formula NaH(C2H3O2)2. It is a salt of acetic acid. It is a colorless solid that is used in seasonings and as an antimicrobial agent.Sodium acetate is produced by reaction of acetic acid with sodium hydroxide. When acetic acid and sodium acetate are mixed in equimolar proportions and allowed to crystallize, the sodium acetate crystallizes with acetic acid of crystallization. This material is called sodium diacetate (E262). It provides a solid source of acetic acid for use in dry products.
Applications:
Sodium bromide NaBr is an inorganic compound with the formula NaBr. It is a high-melting white, crystalline solid that resembles sodium chloride. It is a widely used source of the bromide ion and has many applications.
Applications
Sodium bromide is the most useful inorganic bromide in industry. It is also used as a catalyst in TEMPO-mediated oxidation reactions.
