Uses
Sodium Nitrate is the salt of nitric acid that functions as an antimi- crobial agent and preservative. it is a naturally occurring substance in spinach, beets, broccoli, and other vegetables. it consists of color- less, odorless crystals or crystalline granules. it is moderately deli- quescent in moist air and is readily soluble in water. it is used in meat curing to develop and stabilize the pink color. see nitrate.

Safety Profile
Human poison by ingestion. Poison by intravenous route.Questionable carcinogen with experimental tumorigenic data. Human mutation data reported. A powerful oxidizer. It will iqte with heat or friction. Explodes when heated to over 1000°F, or when mixed with cyanides, sodium hypophosphte, boron phosphide. Forms explosive mixtures with aluminum powder, antimony powder, barium thiocyanate, metal amidosulfates, sodium, sodium phosphinate, sodium thiosulfate, sulfur + charcoal (gunpowder). Potentially violent reaction or ignition when mixed with bitumen, organic matter, calcium-shcon alloy, jute + magnesium chloride, magnesium, metal cyanides, nonmetals, peroxyformic acid, phenol + trifluoroacetic acid. Incompatible with acetic anhydride, barium thocyanate, wood. A dangerous disaster hazard. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and Na2O.
