Chemical Properties and Usage:

 

Chemical Properties white to off-white solid
General Description Minute crystals or white powder. pH of aqueous solutions 5.6 to 7.0 or even higher (a 10% solution, made from a commercial grade, may have a pH of 7.4 to 7.7).
Air & Water Reactions Water soluble. Aqueous solutions are subject to quick air oxidation at pH greater than 6.0.
Reactivity Profile A weak base. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Health Hazard SYMPTOMS: Ingestion of 10 grams or more of this type of compound may cause diarrhea.
Fire Hazard Flash point data for Sodium ascorbate are not available. Sodium ascorbate is probably combustible. .
