Sodium Usage And Synthesis
Chemical Properties light, soft silver metal, readily tarnishing in air.
General Description A silvery soft metal that becomes grayish white upon exposure to air. Shipped as a solid or molten liquid. Burns violently with explosions that may spatter the material. Used for making gasoline additives, electric power cable, Sodium lamps, other chemicals.
Air & Water Reactions May ignite spontaneously in air. Reacts violently with water to give Sodium hydroxide and hydrogen, which ignites spontaneously [Merck, 11th ed. 1989)]. The ignition temperature of Sodium in air depends on the area of surface exposed: vapor ignites at room temperature; droplets at about 250°F; an agitated pool at 400°F. In the absence of moisture and hydrogen, the reaction is insignificant [Mellor 2 Supp. 2:440 1961].
Reactivity Profile Sodium is a powerful reducing agent. Reacts with incandescence with boron trifluoride [Merck 11th ed. 1989]. Reacts explosively with maleic anhydride [Chem Safety Data Sheet SD-88 1962; Chem. Haz. Info. Series C-71 1960]. Explodes on contact with bromoazide. Mixtures with any of the following produce a strong explosion on impact: aluminum bromide, aluminum chloride, aluminum fluoride, ammonium chloride, antimony(III) bromide, antimony(III) chloride, antimony(III) iodide, arsenic(III) chloride, arsenic(III) iodide, bismuth(III) bromide, bismuth(III) chloride, bismuth(III) iodide, boron tribromide, carbon tetrachloride, chromium(IV) chloride, cobalt(II) bromide, cobalt(II) chloride, copper(II) chloride, iron(II) chloride, iron(III) bromide, iron(II) iodide, iodine bromide, manganese(II) chloride, mercury(II) bromide, mercury(II) chloride, mercury(II) fluoride, mercury(II) iodide, mercury(I) chloride, silicon tetrachloride, silver fluoride, tin(IV) chloride, tin(IV) iodide (with sulfur), tin(II) chloride, sulfur dibromide, sulfur dichloride, thallium(I) bromide, vanadium pentachloride, phosphorus pentachloride, phosphorus tribromide, and zinc bromide [Mellor 2 Supp. 2:497 1961]. Reacts with ammonium nitrate to form a yellow explosive substance, thought to be diSodium nitrite [Mellor 8: Supp. 1 546 1964]. Reduces heated bismuth(III) oxide to the metal; the reaction is accompanied by incandescence [Mellor 9:649 1946-47]. Reacts, if finely divided, with bromine with luminescence. Burns spontaneously in moist chlorine. Reacts at room temperature with iodine [Mellor 2 Supp. 1:848 1956]. Reacts explosively with Dry Ice if the two are brought together by impact [Mellor 2 Supp. 2:468 1961]. Forms explosive mixtures with chlorinated hydrocarbons [Chem. Eng. News 26:2604 1948]. Explodes on contact with hydrochloric acid [Mellor 2:469 1946-47]. Explodes with aqueous hydrofluoric acid [Mellor 2:469 1946-47]. Ignites spontaneously in contact with dilute nitric acid [Mellor 2:470 1946-47]. Reacts with dilute sulfuric acid with explosive violence [Mellor 2:470 1946-47]. Sodium ignites on contact with hydroxylamine. (Mellor, 1940, Vol. 8, 292.)
Health Hazard Severe burns caused by burning metal or by caustic soda formed by reaction with moisture on skin.
Fire Hazard Special Hazards of Combustion Products: Fumes of burning Na are highly irritating to skin, eyes, and mucous membranes.
