Potassium sodium tartrate tetrahydrate
CAS 6381-59-5
Alias：Sosiumpotassiumtartrate;POTASSIUM SODIUM TARTRATE REAGENT (ACS)
Molecular formula：C4H12KNaO10
Molecular weight：282.22
Structural formula：
1.Performance and use
Potassium sodium tartrate, also known as sodium-potassium tartrate, Rochelle's salt, Rochelle's salt, is a complex salt formed by sodium tartrate and potassium tartrate. It is colorless to blue-white orthorhombic crystal system, soluble in water, slightly soluble in alcohol, salty and cool taste, aqueous solution is slightly alkaline. 60 ° C when it began to lose the water of crystallization, 215 ° C when it loses all its water of crystallization.
Potassium sodium tartrate can be used as a laxative, food additive (E No. E337), piezoelectric element, and also as a chemical reagent for the preparation of phillipsine reagent, bis-urea reagent, and as a reducing agent in the production of the silver layer on the back of the mirror.
