[Synonyms]: Sodium Tartate, Sodium Tartrate, Sodium DL-Tartrate, Disodium Tartrate, Sodium L-Tartrate, Sodium L-Tartrae, Sodium Citro Tartrate,  Disodium D-Tartrate, Sodium Sulphate Anhy, Disodium DL-tartrate

[Intro]
Sodium tartrate (Na2C4H4O6) is used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings. As a food additive, it is known by the E number E335.
Because its crystal structure captures a very precise amount of water, sodium tartrat is also a common primary standard for Karl Fischer titration, a common technique to assay water content.

[Character]
Colorless crystals or white crystal powder, specific gravity is 1.818, lose two molecular water at 150°C,freely soluable in water, the aqueous solution assumes alkalescence,insuable in alcohol.

[Uses]
Served as minim analytical mensuration of vanadium, the demarcation of Carl Wilhelm Scheele reagent, and is served as screen dose and complexing agent, biochenistry reagent and stabilizer and foodstuff additive etc.
