sodium carbonate

sodium carbonate,

chemical compound, Na₂CO₃, soluble in water and very slightly soluble in alcohol. Pure sodium carbonate is a white, odorless powder that absorbs moisture from the air, has an alkaline taste, and forms a strongly alkaline water solution. It is one of the most basic industrial chemicals. Sodium carbonate decahydrate, Na₂CO₃·10H₂O, is a colorless, transparent crystalline compound commonly called sal soda or washing soda. Because seaweed ashes were an early source of sodium carbonate, it is often called soda ash or, simply, soda. The Solvay processSolvay process
[for Ernest Solvay], commercial process for the manufacture of sodium carbonate (washing soda). Ammonia and carbon dioxide are passed into a saturated sodium chloride solution to form soluble ammonium hydrogen carbonate, which reacts with the sodium chloride to

It is found in large natural deposits and is mined in Wyoming; it is also recovered (with other chemicals) from lake brines in California. The principal uses of sodium carbonate are in the manufacture of glassglass,

a cleansing agent. It cleanses by lowering the surface tension of water, by emulsifying grease, and by absorbing dirt into the foam.

Ancient peoples are believed to have employed wood ashes and water for washing and to have relieved the resulting irritation with

The Leblanc process, the first successful commercial process for making soda, is no longer used in the United States but played a major role in the Industrial Revolution.

sodium carbonate

[′sōd·ē·əm ′kär·bə·nət] (inorganic chemistry) Na₂CO₃ A white, water-soluble powder that decomposes when heated to about 852°C; used as a reagent; forms a monohydrate compound, Na₂CO₃·H₂O, and a decahydrate compound, Na₂CO₃·10H₂O. Also known as soda.

sodium carbonate

a colourless or white odourless soluble crystalline compound existing in several hydrated forms and used in the manufacture of glass, ceramics, soap, and paper and as an industrial and domestic cleansing agent. It is made by the Solvay process and commonly obtained as the decahydrate (washing soda or sal soda) or a white anhydrous powder (soda ash). Formula: Na₂CO₃

sodium carbonate

sodium

[so´de-um] a chemical element, atomic number 11, atomic weight 22.990, symbol Na. (See Appendix 6.) Sodium is the major cation of the extracellular fluid, constituting 90 to 95 per cent of all cations in the blood plasma and interstitial fluid; it thus determines the osmolality of the extracellular fluid. The serum sodium concentration is normally about 140 mEq/L. If the sodium level and osmolality fall, osmoreceptors in the hypothalamus are stimulated and cause the release of antidiuretic hormone from the posterior lobe of the pituitary gland. This hormone increases the absorption of water in the collecting ducts of the kidneys so that water is conserved while sodium and other electrolytes are excreted in the urine. If the sodium level and osmolality rise, neurons in the thirst center of the hypothalamus are stimulated. The thirsty person then drinks enough water to restore the osmolality of the extracellular fluid to the normal level.

A decrease in the serum sodium concentration (hyponatremia) can occur in a variety of conditions. It is often associated with volume" >deficient fluid volume due to diarrhea or vomiting when water is replaced faster than sodium. It can also occur in syndrome of inappropriate antidiuretic hormone, in the late stages of heart failure" >congestive heart failure or cirrhosis of the liver, in acute or chronic renal failure, and in diuretic therapy. An increase in the serum sodium concentration (hypernatremia) occurs when insensible water loss is not replaced by drinking, as in a comatose patient with diabetes insipidus.sodium acetate a source of sodium ions for hemodialysis and peritoneal dialysis, as well as a systemic and urinary alkalizer.sodium ascorbate an antiscorbutic vitamin and nutritional supplement for parenteral administration. It is also used as an aid to deferoxamine therapy in the treatment of chronic iron toxicity.sodium benzoate an antifungal agent also used in a test of liver function.sodium bicarbonate NaHCO₃, a white powder commonly found in households. It has a wide variety of uses in chemistry, in pharmaceuticals, and in consumer products. It is sometimes taken in water as a remedy for acid indigestion but should not be used regularly since when taken in excess it tends to cause alkalosis. It can be mixed with water and applied as a paste for relief of pain in treatment of minor burns and insect bites and stings. A cupful in the bath water may help relieve itching caused by an allergic reaction.

Called also salt.sodium citrate a sodium salt of citric acid, used as an anticoagulant for blood or plasma that is to be fractionated or for blood that is to be stored. It is also administered orally as a urinary alkalizer.dibasic sodium phosphate a salt of phosphoric acid; used alone or in combination with other phosphate compounds, it is given intravenously as an electrolyte replenisher, orally or rectally as a laxative, and orally as a urinary acidifier and for prevention of kidney stones.sodium ferric gluconate a hematinic used especially in treatment of hemodialysis patients with anemia" >iron deficiency anemia who are also receiving erythropoietin therapy. Administered by intravenous injection.sodium fluoride a dental caries preventative used in fluoridation of drinking water or applied topically to teeth.
