Potassium Sodium Tartrate

Scientific name: Rochelle Salt
Molecular formula: KNaC4H4O6•4H2O
Structural formula: Potassium Sodium Tartrate
Molecular weigh: 282.23
CAS NO: 6381-59-5
Character:
Potassium Sodium Tartrate is colorless crystals or white crystal,specific gravity is 1.79,PH value is 6.8~8,the melting point is 70~80°C.Have minute efflorescence in the heat air,lose some water when heated to 60°C,and lose 3 water molecules at 100°C,become salt without water at 215°C. Freely insoluble in water, the Rochelle Salt solution assumes minute alkalescence.
Uses:
Potassium Sodium Tartrate is used as reducer in plating of printing, mirror, and thermos industries; as complexing agent in electroplating industry;as laxative agent in pharmacy in the making of crystal speakers and microphones in telecom industry; as desalting agent in chemical fertilizer industry; and also used in glass industry and other industries.

Specifications: US FCC(IV)
