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 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a
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.

The prefix bi-is a deprecated way of indicating the presence of a single hydrogen ion, as in "sodium bicarbonate" (NaHCO 3). The modern method specifically names the hydrogen atom. Thus, NaHCO 3 would be pronounced sodium hydrogen carbonate. Positively charged ions are called cations and negatively charged ions are called anions.

Examples of important inorganic sodium salts are sodium fluoride, sodium chloride, sodium bromide, sodium iodide, sodium sulfate, sodium bicarbonate and sodium carbonate. Sodium amide (NaNH 2) is the sodium salt of ammonia (NH 3).
Nahcolite is a soft, colourless or white carbonate mineral with the composition of sodium bicarbonate (Na H C O 3) also called thermokalite. It crystallizes in the monoclinic system. [4] Nahcolite was first described in 1928 for an occurrence in a lava tunnel at Mount Vesuvius, Italy. [2] Its name refers to the elements which compose it: Na, H ...
