![]() Sodium metal can be used as a heat exchanger in certain nuclear reactors and is generally used in the chemicals industry.Although it is a metal, when at room temperature sodium can be cut through with a butter knife!.In fact, sodium is also critical to the function of the human nervous system and to muscular contractions. In humans, sodium is essential to cellular function for many reasons to maintain fluid balance in the cells and the rest of the body, and for the absorption of nutrients such as glucose. Sodium is an essential element for the nutrition of animals, people and some plants, and humans have known this since prehistoric times.The colour is so bright that it is not usually used with others because it masks them. Another explosive fact: the use of sodium in fireworks is what gives them the gold or yellow colour.It is a highly reactive element: as a pure element sodium has to be kept under oil or kerosene – when exposed to water it ignites.Although shiny and beautiful, sodium tarnishes within a few seconds when it is exposed to the air.Sodium ions have therefore been seeping out of the earth’s minerals for eons. This is due to the fact that sodium is highly water soluble. On top of being highly abundant in the Earth’s crust, sodium and chloride also happen to be the most common dissolved elements (as measured by weight) in the oceans.Despite this, it comprises of about 2.6% of the Earth’s crust, making it the most abundant alkali metal and the sixth most abundant element on Earth, where it exists in minerals such as rocksalt, feldspars, and sodalite.As a free metal, sodium does not exist in nature and must be prepared from its compounds, which have been used for centuries.Cooled Carousel 6 Plus Reaction Station.Cooled Carousel 12 Plus Reaction Station.Rotary vane pumps and chemistry-HYBRID pumps.Classic Open Bath and Circulation Thermostats.The pure metal is priced at $25 for every 100 gram. The human body contains around 100 grams of sodium.The metal is soft enough to be cut with the edge of a coin.Low sodium foods include frozen lamb, eggs, uncanned dry peas and beans, low sodium peanut butter, etc. Foods high in sodium are canned fish, meat, entrees, beans, salted nuts, etc. Any extra sodium may be harmful and cause high blood pressure and other ailments. An average person intakes 10 grams of salt a day though the recommended daily sodium intake (RDA) is just 3 grams. Human beings usually get the required sodium from their food. Na is essential to all living beings as it is vital for the maintenance of different functions of the body. Sodium vapor used in streetlights gives off a brilliant yellow light.Sodium carbonate, another sodium salt, is also known as washing soda and is used as a water softener.It also finds application as a feedstock in the chemical industry. Common salt or sodium chloride is added to food to enhance its taste and as a de-icing agent for roads in winter. Its salts have more uses than the metal itself.As a reagent in the chemical industry.As a heat exchanger in nuclear reactors.Lewis Dot Structure for Sodium Sodium Uses If a small piece of Na is dropped into ethanol, it reacts steadily releasing bubbles of hydrogen gas leaving behind a colorless solution of sodium ethoxide. It dissolves readily in dilute sulphuric acid. It reacts vigorously with all the halogens (chlorine, fluorine, etc.) forming sodium halides. During the exothermic reaction, the metal may become so hot that it may catch fire and burn with an orange-colored flame. Sodium reacts rapidly with water to produce a colorless solution of sodium hydroxide (a base) and hydrogen gas. When burnt in air (oxygen), it forms white sodium peroxide and sodium oxide. Besides that, it has 16 synthetic, radioactive isotopes with known half-lives. Naturally occurring Na is its most stable isotope with mass number 23. Sodium (pronunciation SO-dee-em ), represented by the chemical symbol or formula Na, is a soft, malleable element belonging to the family of alkali metals. Properties and Characteristics of Sodium.
