Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation ( Na + ) and a bicarbonate anion ( HCO 3 − ).
Solanum tampicense plant. The stems of Solanum tampicense can reach up to 5 m in length and 1.5 cm in diameter. The leaves are of the simple form and are attached in an alternate arrangement on the stem. Individual blades may be up to 25 cm in length and 7 cm in width. The flowers are small and are clustered in groups of 3 to 11.
It is one of several plants also known as bindi weed, bindii, or bindi-eye. A weedy plant known for its tiny sharp-needled seeds. It appears with small feathery leaves reminiscent of parsley, with an exposed upward-pointing rosette of seeds in a pod nestled at the branch junctions. Eventually small flowers appear if the plant is allowed to develop.
Before "soda" was somewhat synonymous (in U.S. English) with soft drinks, the word referred to Salsola soda and other saltwort plants, and to soda ash. While the era of farming for soda ash is long past, S. soda is still cultivated as a vegetable that enjoys considerable popularity in Greece, Italy and with gourmets around the world.
The word "barilla" was also used directly to refer to soda ash from any plant source, including not only the saltworts grown in Spain, but also glassworts, mangroves, and seaweed. [6] These types of plant-derived soda ash are impure alkali substances that contain widely varying amounts of sodium carbonate (Na 2 CO 3 ), some additional potassium ...
Soda ash is an alkali whose active ingredient is now known to be sodium carbonate. Glasswort and saltwort plants sequester the sodium they absorb from salt water into their tissues (see Salsola soda). Ashing of the plants converts some of this sodium into sodium carbonate (or "soda", in one of the old uses of the term). [citation needed]
The worldwide production of soda ash in 2005 was estimated at 42 million tonnes, [2] which is more than six kilograms (13 lb) per year for each person on Earth. Solvay-based chemical plants now produce roughly three-quarters of this supply, with the remaining being mined from natural deposits. This method superseded the Leblanc process.
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.
