Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.

There are 20 isotopes of sodium ( 11 Na), ranging from 17. Na to 39. Na (except for the still-unknown 36 Na and 38 Na), [4] and two isomers ( 22m. Na and 24m. Na ). 23. Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2).
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms ( tachycardias ), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia . Many attempts have been made to classify antiarrhythmic agents.
Sodium oxide is a chemical compound with the formula Na 2 O.It is used in ceramics and glasses.It is a white solid but the compound is rarely encountered. Instead "sodium oxide" is used to describe components of various materials such as glasses and fertilizers which contain oxides that include sodium and other elements.
Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).
Narcotics Anonymous ( NA ), founded in 1953, describes itself as a "nonprofit fellowship or society of men and women for whom drugs had become a major problem." [1] Narcotics Anonymous uses a 12-step model developed for people with varied substance use disorders [2] and is the second-largest 12-step organization, [3] after 12-step pioneer ...
Renal reabsorption of sodium ( Na +) is a part of renal physiology. It uses Na-H antiport, Na-glucose symport, sodium ion channels (minor). [1] It is stimulated by angiotensin II and aldosterone, and inhibited by atrial natriuretic peptide . It is very efficient, since more than 25,000 m moles /day of sodium is filtered into the nephron, but ...
