Description
Mono sodium tartrate or sodium bitartrate is a sodium salt of tartaric acid. As a food additive it is used as an acidity regulator and is known by the E number E335.
Chemical Properties
White, crystalline powder.Soluble in
water (aqueous solution in acid); slightly soluble in
alcohol. Combustible.
Uses
Sodium hydrogen L-tartrate is used for detecting potassium and in nutrient media. It also used as a food additive and an acidity regulator.
Uses
Analysis (testing for potassium), effervescing
mixture, nutrient media.
Uses
Sodium hydrogentartrate may also be used in the preparation of sodium citrate-sodium tartrate reagent, which can complex with interfering metals during the colorimetric estimation of ammonium ions in soil samples. The modification of supported nickel catalysts with sodium hydrogentartrate leads to enhanced enantiomeric excess (ee) during the hydrogenation of methyl acetoacetate.
General Description
Sodium hydrogentartrate is an inorganic salt commonly used in qualitative chemical analysis to detect potassium.
Purification Methods
It crystallises from warm water (10mL/g) by cooling to 0o. [Beilstein 3 IV 1219.]
