The modern way of analyzing the situation based on the exact chemical composition (which was unknown when the name “sodium bicarbonate” was coined) says this the other way around: there is half as much sodium in NaHCO3 as in Na2CO3 (Na versus Na2). The word saleratus, from Latin sal æratus meaning “aerated salt”, was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate.The prefix “bi” in “bicarbonate” comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO3) per sodium in sodium bicarbonate (NaHCO3) as there is carbonate per sodium in sodium carbonate (Na2CO3) and other carbonates. Forms such as sodium bicarb, bicarb soda, bicarbonate, bicarb, or even bica are common. In colloquial usage, the names sodium bicarbonate and bicarbonate of soda are often truncated. To the finest of our information, no scholar in present day times has ever tried to answer these questions. Since Herodotus portrayed the ancient Egyptians usage of natron salt in embalming process, numerous questions have arisen with respect to the exact strategy of use. Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. The Use of Natron in Human Mummification. It is among the food additives encoded by the European Union, identified as E 500. It is a component of the mineral natron and is found dissolved in many mineral springs. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). Sodium bicarbonate is a White solid that is crystalline but often appears as a fine powder. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is a chemical compound with the formula NaHCO3.
