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.
