Sodium tartrates is used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings.
As a food additive, Sodium tartrates is known by the E number E335.
Because Sodium tartrates's crystal structure captures a very precise amount of water, it is also a common primary standard for Karl Fischer titration, a common technique to assay water content.

White crystals or granules.
Soluble in water; insoluble in alcohol.
The organic sodium salt that is the disodium salt of L-tartaric acid.
Sodium tartrates is a salt used as an emulsifier and a binding agent in food products such as jellies, margarine, and sausage casings.
As a food additive, Sodium tartrates is known by the E number E335.
Sodium tartrates is made by the combination reaction of baking soda/sodium bicarbonate (NaHCO3) with tartaric acid.
Because its crystal structure captures a very precise amount of water, Sodium tartrates is also a common primary standard for Karl Fischer titration, a common technique to assay water content.
