Sodium Acetate Anhydrous - pH Buffer Solution, Concrete Additive, Heat Storage Material
Sodium acetate anhydrous (CH₃COONa) is a white crystalline powder or granular material with minimal odor. This versatile organic acid salt features unique properties including hygroscopicity, high water solubility, alkaline aqueous solution, freezing point depression, and phase-change heat storage capabilities. Its applications span traditional chemical processing to modern energy storage and building material technologies.
