Descrizione

Descrizione generale

Potassium sodium tartrate tetrahydrate, commonly called as Rochelle salt, is a ferroelectric crystal[1] with high piezoelectric effect. It is deliquescent and water soluble with highest electromechanical coupling coefficient.[2] It is a component of DNS (3,5-dinitrosalicylic acid) reagent, a colorimetric reagent[3][4][5] and Fehling′s solution B which are used in the determination of reducing sugar.[6] NMR spectra and the spin-lattice relaxation times has been reported.[7]

Applicazioni

Potassium sodium tartrate tetrahydrate may be used in the following processes:

• Polyphenol assay.[8]
• Synthesis of iron nanoparticles, whcih are used in the synthesis of amorphous carbon nanofibers.[9]
• As a component in the reservoir solution used to induce crystallization of proteins.[10]
• As a component of aqueous plating solution for electroless silver deposition on polycarbonate substrates.[11]
