Sodium Acetate vs. Sodium Acetate Trihydrate: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 27, 2023
Sodium acetate is a sodium salt of acetic acid, anhydrous; sodium acetate trihydrate contains three water molecules.

Key Differences

Sodium acetate is a chemical compound with the formula CH3COONa, used in various industrial and laboratory processes. Sodium acetate trihydrate, on the other hand, is the hydrated form of sodium acetate, containing three molecules of water (H2O) for each unit of sodium acetate.
