SODIUM SULFITE
Chemical Designations - Synonyms: No common synonyms; Chemical Formula: Na$03.
Observable Characteristics - Physical State (us shipped): Solid; Color: White; Odor: Odorless.
Physical and Chemical Properties - Physical State at 15 'C and I am. : Solid; Molecular Weight:
126.04; Boiling Point at I atm. : Decomposes; Freezing Point: Not pertinent; Critical Temperature: Not
pertinent; Critical Pressure: Not pertinent; Spec@c Gravity: 2.633 at 15 "C (solid); Vapor (Gar)

Health Hazards Information - Recommended Personal Protective Equipment: Dust mask; goggles or
face shield; Symptoms Following Exposure: When ingested, solutions cause gastric irritation by the
liberation of sulfurous acid. Because of rapid oxidation to sulfate, sulfites are well tolerated until large
doses are reached; than violent colic and diarrhea, circulatory disturbances, central nervous depression,
and death can occur; General Treatment for Exposure: INGESTION: treatment is symptomatic and
supportive; call a doctor; Toxicity by Inhalation (Threshold Limit Value): Not pertinent; Short-Tern
