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
One idea is to react carbon dioxide, produced perhaps by the combustion of coal, to form solid carbonates (such as sodium bicarbonate) that could be permanently stored, thus avoiding carbon dioxide emission into the atmosphere. [20] [21] The Solvay process could be modified to give the overall reaction: 2 NaCl + CaCO 3 + CO 2 + H 2 O → 2NaHCO ...
An aqueous solution of cobalt(II) nitrate and hydrogen peroxide is added to a solution of sodium bicarbonate, leading to precipitation of the olive solid. [2] The method is a modification of the synthesis of what has been described as “Co 2 (CO 3) 3 ”. [3]
U.S. consumer-packaged baking powder. This particular type of baking powder contains monocalcium phosphate, sodium bicarbonate, and cornstarch. Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid. The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as ...
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).
It is isoelectronic with nitric acid HNO 3. The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 ...
An obvious synthesis route to α-alaninediacetic acid is from racemic α-DL-alanine, which provides racemic α-ADA by double cyanomethylation with methanal and hydrogen cyanide, hydrolysis of the intermediately formed diacetonitrile to the trisodium salt and subsequent acidification with mineral acids in a 97.4% overall yield.

A simple sodium bicarbonate buffer system is commonly employed to alleviate this issue, which is especially problematic in bicyclic and other complex molecule syntheses (see synthetic examples). [ 1 ] [ 20 ] The introduction of chiral oxidants has also allowed for the synthesis of enantiopure α-hydroxy carbonyl derivatives from their ...
