Potassium Sodium Tartrate
C4H4KNaO6·4H2O 282.22
Butanedioic acid, 2,3-dihydroxy-, [R-(R*,R*)]-, monopotassium monosodium salt, tetrahydrate.
Monopotassium monosodium tartrate tetrahydrate CAS 6100-16-9 and CAS 6381-59-5
Anhydrous 210.16 CAS 304-59-6
Potassium Sodium Tartrate contains not less than 99.0 percent and not more than 102.0 percent of C4H4KNaO6, calculated on the anhydrous basis.
Identification—
A: Ignite it: it emits the odor of burning sugar and leaves a residue that is alkaline to litmus and that effervesces with acids.
B: To 10 mL of a solution (1 in 20) add 10 mL of 6 N acetic acid: a white, crystalline precipitate is formed within 15 minutes.
C: A solution (1 in 10) responds to the tests for Tartrate.
TESTS
Meets all the tests for Specifications of Potassium Sodium Tartrate Tetrahydrate USP mongograph.

Potassium Sodium Tartrate; Rochelle Salt; Seignette Salt
KOOCCH(OH)CH(OH)COONa·4H2O
C4H4KNaO6·4H2O Formula weight 282.22
INS: 337 CAS 304-59-6
DESCRIPTION
Sodium Potassium Tartrate occurs as colorless crystals or as a white, crystalline powder. As it effloresces slightly in warm, dry air, the crystals are often coated with a white powder. It is a salt of L(+)-tartaric acid. One gram dissolves in 1 mL of water. It is practically insoluble in alcohol.
Function: Buffer; sequestrant.
REQUIREMENTS
Identification:
A. Upon ignition, a sample emits the odor of burning sugar and leaves a residue that is alkaline to litmus and that effervesces with acids.
B. Add 10 mL of acetic acid to 10 mL of a 1:20 aqueous solution. A white, crystalline precipitate forms within 15 min.
C. A1:10 aqueous solution gives positive tests for Tartrate.
Assay: Not less than 99.0% and not more than 102.0% of C4H4KNaO6·4H2O after drying.
Alkalinity: Passes test.
Lead: Not more than 2 mg/kg.
Water: Between 21.0% and 26.0%.
