Product Overview
Potassium sodium tartrate 4-hydrate, also known as Rochelle salt, is a high-purity ACS reagent-grade crystalline compound widely used in analytical chemistry and volumetric analysis. This chemically stable salt forms colorless or white crystals that are highly soluble in water, making it ideal for preparing standard solutions and buffer systems. The BAKER ANALYZED™ certification ensures strict adherence to American Chemical Society (ACS) specifications, guaranteeing minimal impurities and consistent performance in critical laboratory procedures. Its precise molecular composition (KNaC₄H₄O₆·4H₂O) provides reliable stoichiometric reactions, particularly in redox titrations and as a complexing agent. The crystalline form offers excellent shelf stability when stored under recommended conditions, maintaining its efficacy over extended periods. This reagent is particularly valued for its role in Fehling’s solution preparation and as a resolving agent in chiral separations. The 500g pack size provides an optimal balance between bulk requirements and freshness maintenance for regular laboratory use.
