A once-common use was the making of tetraethyllead and titanium metal; because of the move away from TEL and new titanium production methods, the production of sodium declined after 1970. [22] Sodium is also used as an alloying metal, an anti-scaling agent, [69] and as a reducing agent for metals when other materials are ineffective.
Other common uses of sodium hydroxide include: for making soaps and detergents. Sodium hydroxide is used for hard bar soap, while potassium hydroxide is used for liquid soaps. [30] [31] Sodium hydroxide is used more often than potassium hydroxide because it is cheaper and a smaller quantity is needed.
Sodium compounds. Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.
Sodium chloride / ˌsoʊdiəm ˈklɔːraɪd /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic, and occurs as the mineral halite. In its edible form, it is commonly used as a condiment and food ...
The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate[9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3−). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.
Herbicides are often used as sodium salts for the reasons discussed above. One example is the sodium salt of methylflupyrsulfuron (CAS-No. 144740-54-5). [2] Cosmetics
It is often used to give potato chips a salt and vinegar flavour, and may be used as a substitute for vinegar itself on potato chips as it does not add moisture to the final product. [11] Sodium acetate (anhydrous) is widely used as a shelf-life extending agent and pH-control agent. [12] It is safe to eat at low concentration. [13]
