sodium natrij Sodium was discovered by Sir Humphry Davy (England) in 1807. The origin of the name comes from the Latin wordnatriummeaningsodium carbonate. It is soft silvery-white metal. Fresh surfaces oxidize rapidly. Reacts vigorously, even violently with water. Reacts with water to give of...
Sodium is a soft, silvery alkali metal and reacts vigorously with water to generate hydrogen gas. The word sodium is derived from "sodanum" (a Medieval Latin name for a headache remedy), and "natrium" (Latin for "soda") is the origin of the element's symbol. Humphry Davy isolated the...
Sodium burns in air with a brilliant yellow flame. Sodium floats on water, because its density is lower than water’s. It also reacts vigorously with water – violently if more than a small amount of sodium meets water (see video on left) – to produce sodium hydroxide andhydrogengas. So...
1 , 4-6 Handling, Storage, and Precautions: sodium metal reacts violently with water to produce flammable H 2 gas. High sodium-containing Na/Al 2 O 3 catalysts may be pyrophoric. In case of fire, do not expose to water, CO 2 , or vaporizable liquids. The activity of the catalyst ...

When water or moisture reacts strongly to release hydrogen, a large amount of heat, causing combustion or explosion. Exposure of metallic sodium to air or oxygen can burn itself and cause an explosion of molten matter to splash. Reacts vigorously with halogens, phosphorus, many oxides, ...
Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard. /Sodium methylate; Sodium methylate, dry//GUIDE 138: ...
Sodium reacts vigorously with sulfur to yield sodium sulfide. The reaction of sodium vapors with nitrogen in a silent discharge field leads to the formation of sodium nitride, Na3N; reaction with carbon at 8O0°-9O0°C yields sodium carbide, Na2C2. Sodium dissolves in liquid ammonia (34.6 ...
with an orange-colored flame. It reacts vigorously with all the halogens (chlorine, fluorine, etc.) forming sodium halides. It dissolves readily in dilute sulphuric acid. If a small piece of Na is dropped into ethanol, it reacts steadily releasing bubbles of hydrogen gas leaving behind a ...
(chemiluminescence). Halogen acids, such ashydrochloric acid, react vigorously with sodium,yieldingthe sodium halides. The reactions are highly exothermic, with heats of reaction (energy given off) of −71.8 and −76.2 kcal, respectively, for the reactions with hydrofluoric and hydrochloric acids....
