Application

Potassium sodium tartrate tetrahydrate can be used as a:
  • Reducing agent in the preparation of monodispersed gold nanoparticles.
  • Key component in the preparation of Fehling′s solution, which is used to distinguish between reducing and non-reducing sugars.
  • Chelating agent to prepare Co-Ni-P/Pd-Al2O3 catalyst through electroless deposition method.
