Heat of Crystallization

PIRA DCS: 4C-20.60


Phase Change, Latent Heat, Crystal Growth
Sodium Acetate (anhydrous): NaC2H3O2
Sodium Acetate Trihydrate: NaC2H3O2•3H20
Phase Change: Na+ + C2H3O2- + 3H20 → NaC2H3O2•3H20 (solid) + 4 Kilocalories/mole
Safety Issues
Sodium acetate is used as a food preservative and is classified as a food grade material.
