Recommended 5g salt (sodium = 2000mg) a day in the World Health Organization.
Toxicity can occur when at least 14g of sodium intake per day.
We are also familiar with the name of the sodium (Natrium) Sodium (Sodium) is. A constituent element of the sodium salt, and has been considered to be essential to the maintenance of human life since ancient poly times. However, the warning could also be the cause of many diseases of excessive sodium intake recently. Sodium is an element and, where used, let's look at whether any sodium compounds.
A single element with atomic number 11, the element symbols poly are sodium Na (sodium) is. One belonging poly to the group 1 of the periodic table (1A Group) an alkali metal element. Mureugo enough to cut with a knife, is a silvery white, very large reactivity. Creates an oxide to react quickly with the oxygen in the air is sodium, reacts explosively with water vigorously. Keep them in a non-oxidizing material such as (for example oil) and liquid hydrocarbon, because the size of reactive.
In nature, there are only a compound of sodium. With salt and soda, is the most well-known chemical names of these compounds are sodium chloride, respectively sodium (NaCl) and sodium carbonate (Na 2 CO 3, and a hydrate). poly The second abundant element in the earth, which accounts for about 2.6% of the shell weight of sodium poly is 06. Many aluminum (Al), iron (Fe), calcium (Ca), magnesium (Mg) followed by a metal. It contains about 30g of salt in seawater 1L, accounted for 39% of the sodium salt weight. The remaining rock salt was evaporated from the sea to the distant past where the water after primary sodium ore. And contains a lot of minerals, such as sodium carbonate, nitrate, sulfate, borate, ice-static, poly and zeolite. Unlike the elemental sodium poly metal, it may be handled with bare hands to stabilize the sodium compound, most. However, like sodium hydroxide (caustic soda, NaOH) is dangerous and should be treated with caution, some compounds.
Is used as a reducing agent, such as sodium (sodium, etc.), coolant (by using a fast neutron nuclear reactor) in a high-speed growth, an alloy material of the metal state is sodium. The presence of a cation in the ionic compound is sodium. poly Is essential for life in all animals, sodium cations (Na +) are also some plants poly are necessary. poly Etc. involved with the osmotic pressure in the body moisture, balancing the acid, alkali, Na + is a neurotransmitter.
Been used for a long time an important compound of sodium carbonate and sodium salt is. Align the liver of food pickled foods have long been used to preserve the salt again. Was used to wash the glass manufacturing and sodium carbonate is obtained from potash. Was used in medieval Europe to Latin bulrideon called 'sodanum' poly cure headaches, it seems from the Arabic 'suda' meaning, perhaps poly a headache. The headache treatment is inde chemically sodium poly carbonate, called soda (soda) la in English. Sodium hydroxide was obtained by reacting sodium carbonate with water to roast. Sodium bicarbonate (baking soda, NaHCO are used by many means "soda" right chemically, tteuthana crystalline sodium poly carbonate (Na 2 CO 3 10H 2 O) is a narrow, sodium bicarbonate or baking soda is widely known 3-D ) and caustic soda, also called 'soda'. In addition gongeopgye sometimes called poly soda ash (soda ash) and anhydrous sodium carbonate. And say beverages Normal acid (2 CO) gas is a soda, which is condensed with the sodium bicarbonate to sodium carbonate to obtain a gas in the past.
(H. Davy, 1778 ~ 1829) The sodium is Davy in 1807 for the first time in the UK by the state as separate elements. poly He separating the molten elemental sodium hydroxide by the electrolysis and after 'sodanum' and was named sodium poly (sodium) poly is called. Was made after a few days only whether the separation of potassium (potassium, K) of sodium are separated in the same way. The proposal made by Berzelius (JJ Berzelius, 1779 ~ 1848) is another name in 1814 in sodium sodium (Natrium) and Na is the element symbol. He adopted the name as an element of the natural mineral natron ancient Egyptian name of sodium carbonate, the main component of its Latin name natrium first element was to sign a two-letter Na.
11 has an E-atom is sodium. 2s 2 2p 6 3s 1, is [Ne] 1 a 1s 2 3s that is to be added to a higher energy state E 1 to the electron configuration of the inert gas of neon (Ne) electronic arrangement. Therefore it is a stable electron configuration such as neon and very easy to lose one electron is Na + is the Na. Ionization energy, the electron poly affinity of the alkali metal element, melting point, tends to both write the larger atomic number (that is low), the boiling point is. Accordingly, about the middle of the corresponding value for a lithium (Li) and potassium (K) approximately, these values are for the sodium. On the other hand, density of the larger atomic number, but generally higher, rather than the high potassium 0.856g / cm 3 to 0.968g / cm 3 of the sodium density. The sodium is a good electrical and thermal conductor.
To figure the characteristic flame colors are alkali poly metal element, the sodium flame color is dark yellow. Is made up of two lines, which is very close to the line referred to as sodium D- (D-line) poly with a yellow line of the sodium spectrum. 3s is due to electronic transitions of sodium D- lines generated are reduced Na + is the flame is in the sodium atom 3p . In contrast, is due to the red color of the Li + Li flame.
Only stable isotope of sodium is 23 Na thing, almost everyone is a natural poly state of Na 23 Na. Been made to trace 22 Na and 24 Na by the ship, and the half-life of 22 Na was 2.6 years, the half-life of 24 Na is 15 hours. When the human body is exposed to a neutron beam may be converted into a part 24 Na 23 Na in the blood. So can be calculated by measuring the concentration of the 24 Na neutron beam dose during nuclear accidents.
Dissolved in liquid ammonia (NH 3) are the alkali metals including sodium. All of the ammonia solution of an alkali metal concentration in the dilute Blue, and the concentrations of the copper-colored ttinda. Paramagnetic showed poly a weak solution is greater than about 10 times the electrical conductivity of an aqueous solution of metal salt. Is described as being due to action as a free electron-electron is enclosed in a solvent as a cation (M +) in liquid poly ammonia, an alkali metal (M) they show similar unique properties such as this.
May be mentioned sodium carbonate (Na 2 CO 3) is called soda, soda ash, laundry is (washing soda), etc. The next important are sodium compounds. The monohydrate form of the white powder is easily punghae sodium carbonate is usually present in form of a hydrate having a number of water molecules. Prior to the industrial production of sodium carbonate, and evaporated to give the water in the salt-resistant plants often missed or ride the rest of the algae re-lye. Was done by the (1742 ~ 1806 N. Leblanc,) LeBlanc in 1791 industrial production of soda is. In the Leblanc process, sulfuric acid (H 2 SO 4) and by the reaction of sodium sulfate salt gained (Na 2 SO 4), get a soda, in tune with the limestone (CaCO 3) and coal (C).
Na 2 CO 3 is produced in the world is about 33 million tons (as of 1999), is synthesized by the Solvay method (ammonia sodabeop) 70% thereof is obtained from a natural mineral called Trojan or (trona) remaining. I Tropez such as natron in ancient Egypt and the origin poly of minerals sodium (natrium), and a formula of Na 3 H (CO 3) 2 2H 2 O. There are many stores where I Tropez world, the reserves of more than 100 million tons of Wyoming is on the banks of the United States (Wyoming) Day Green River (Green river) in particular. In the past, Na 2 CO 3 has been widely used mainly in washing soda for about half of the production of glass-making, and the alkali is used in about a quarter of the steel by the appearance of the laundry detergents they are rarely used today.
Making sodium bicarbonate (NaHCO 3) is synthesized by Solvay method, or a NaOH aqueous solution poly (2 CO), carbon dioxide poly blow. When you burn the bread is used to inflate the property by putting out carbon dioxide as easily decomposed at least 70 o C sodium bicarbonate poly (NaHCO 3), and is also the raw material of foamed synthetic carbonated juice powder, used a lot. Addition is used as animal feed additives, chemicals, and extinguishing fires.
However, poly to get the brine electrolysis of caustic soda almost now. Caustic soda is produced about 60 million tons year worldwide, double used directly in the manufacture of chemicals about 50%, based on chemicals used in a wide range of industries such as the paper industry, food industry, textile industry, soap and detergent industries rest The. And may be a material such as to neutralize or increase the alkalinity, an acidic solution used is sodium hydroxide. Reacted with acids of caustic soda is obtained poly sodium salt is substantially soluble in water, they most. Create a wide variety of sodium salts are used in many applications.
To obtain poly a molten metal, poly mainly the sodium salt by the electrolysis current. The electrolysis down to below 700 o C that the mixed salt (CaCl 2), because the melting point of the salt melting time high as 801 o C. In this case is obtained with chlorine (Cl 2), the substance which is an important basic material for chemical industry. Obtained by thermal decomposition of sodium azide Chemistry (NaN 3) pure sodium metal. Few, if used directly as a source of sodium is sodium metal compound is obtained by using NaOH, Na 2 CO 3 and the like, most sodium compound. poly
