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 − ).
The postal abbreviation is the same as the ISO 3166-2 subdivision code for each of the fifty states. These codes do not overlap with the 13 Canadian subnational postal abbreviations. The code for Nebraska changed from NB to NE in November 1969 to avoid a conflict with New Brunswick. [4]
The codes were assigned by NIST and each uniquely identified a state, the District of Columbia, or an outlying area of the U.S. These codes were used by the U.S. Census Bureau, the Department of Agriculture to form milk-processing plant numbers, some cash registers during check approval, and in the Emergency Alert System (EAS).
Most states use a single official code divided into numbered titles. Pennsylvania's official codification is still in progress. California, New York, and Texas use separate subject-specific codes (or in New York's case, "Consolidated Laws") which must be separately cited by name.
Sodium bicarbonate (NaHCO 3) or baking soda, also a component in fire extinguishers, is often generated from sodium carbonate. Although NaHCO 3 is itself an intermediate product of the Solvay process, the heating needed to remove the ammonia that contaminates it decomposes some NaHCO 3 , making it more economical to react finished Na 2 CO 3 ...
Baking powder is made up of a base, an acid, and a buffering material to prevent the acid and base from reacting before their intended use. [5] [6] Most commercially available baking powders are made up of sodium bicarbonate (NaHCO 3, also known as baking soda or bicarbonate of soda) and one or more acid salts.
In diagnostic medicine, the blood value of bicarbonate is one of several indicators of the state of acid–base physiology in the body. It is measured, along with chloride, potassium, and sodium, to assess electrolyte levels in an electrolyte panel test (which has Current Procedural Terminology, CPT, code 80051). [citation needed]
