Potassium sodium tartrate was known as Seignette's salt or Rochelle salt. Rochelle salt is not to be confused with rock salt, which is simply the mineral form of sodium chloride. Potassium sodium tartrate and monopotassium phosphate were the first materials discovered to exhibit piezoelectricity.
Used as masking agent and complexing agent in analysis, for formulating Fehling's solution and determining uric acid and seroglycoid, its monocrystals can be used as piezoelectric cell.
