Sodium Phosphite
Disodium hydrogen phosphite is the name for inorganic compounds with the formula Na2HPO3.(H2O)x. The commonly encountered salt is the pentahydrate. A derivative of phosphorous acid (HP(O)(OH)2), it contains the anion HPO32−. Its common name suggests that it contains an acidic hydrogen atom, as in sodium hydrogen carbonate Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate), 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 ( HCO3∠.... However, this name is misleading as the hydrogen atom is not acidic, being bonded to phosphorus rather than oxygen. The salt has reducing properties. It is white or colorless solid, and is little studied. References Phosphites Inorganic phosphorus compounds Sodium compounds {{Inorganic-compound-stub ...

Inorganic Compound
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. Some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, etc.), carbon monoxide, carbon dioxide, carbides, and the following salts of inorganic anions: carbonates, cyanides, cyanates, and thiocyanates. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it does not occur within living things. History Friedrich Wöhler's conversion of ammonium cyanate into urea in 1828 is often cited as the starting point of modern ...

Phosphorous Acid
Phosphorous acid (or phosphonic acid (singular)) is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO3H2, are called phosphonic acids. Nomenclature and tautomerism H3PO3 is more clearly described with the structural formula HPO(OH)2. In the solid state, has tetrahedral geometry about the central phosphorus atom, with a P–H bond of 132 pm, one P=O double bond of 148 pm and two longer P–O(H) single bonds of 154 pm. This species exists in equilibrium with an extremely minor tautomer . IUPAC recommends that the latter be called phosphorous acid, whereas the dihydroxy form is called phosphonic acid.. Only the reduced phosphorus compounds are spelled with an "ous" ending. Other important oxyacids of pho ...

Sodium Bicarbonate
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate), 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 ( HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs. Nomenclature Because it has long been known and widely used, the salt has many different names such as baking soda, bread soda, cooking soda, and bicarbonate of soda and can often be found near baking powder in stores. The term ''baking soda'' is more common in the United States, while ''bicarbonate of soda'' is more common in Australia, United Kingdom and Ireland. and in many northern/central European countries it is called ''Na ...

Phosphites
A phosphite anion or phosphite in inorganic chemistry usually refers to PO3sup>2− but includes 2PO3sup>− ( PO2(OH)sup>−). These anions are the conjugate bases of phosphorous acid (H3PO3). The corresponding salts, e.g. sodium phosphite (Na2HPO3) are reducing in character. Nomenclature The IUPAC recommended name for phosphorous acid is phosphonic acid. Correspondingly, the IUPAC-recommended name for the ion is phosphonate. In the US the IUPAC naming conventions for inorganic compounds are taught at high school, but not as a 'required' part of the curriculum. A well-known university-level textbook follows the IUPAC recommendations.Egon Wiberg, Arnold Frederick Holleman (2001) ''Inorganic Chemistry'', Elsevier In practice any reference to "phosphite" should be investigated to determine the naming convention being employed. Salts containing , called phosphonates or phosphites : From the commercial perspective, the most important phosphite salt is basic lead phosphite. ...
