  2. Sodium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bicarbonate

    3 + H 2 O → H 2 CO 3 + OH −. Sodium bicarbonate can sometimes be used as a mild neutralization agent and a safer alternative to strong bases like sodium hydroxide. [79] Reaction of sodium bicarbonate and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water: [79] NaHCO 3 + HCl → NaCl + H 2 O+CO 2 ...

  3. Solvay process - Wikipedia

    en.wikipedia.org/wiki/Solvay_process

    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 ...

  4. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    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 with ...

  5. Bicarbonate buffer system - Wikipedia

    3] is the concentration of bicarbonate in the blood [H 2 CO 3] is the concentration of carbonic acid in the blood; When describing arterial blood gas, the Henderson–Hasselbalch equation is usually quoted in terms of pCO 2, the partial pressure of carbon dioxide, rather than H 2 CO 3 concentration.

    14 nahco 3 + 5 ca(h 2 po 4) 2 → 14 co 2 + ca 5 (po 4) 3 oh + 7 na 2 hpo 4 + 13 h 2 o Monocalcium phosphate ("MCP") is a common acid component in domestic baking powders. A typical formulation (by weight) could call for 30% sodium bicarbonate, 5–12% monocalcium phosphate , and 21–26% sodium aluminium sulfate .

  7. Disodium pyrophosphate - Wikipedia

    en.wikipedia.org/wiki/Disodium_pyrophosphate

    It combines with sodium bicarbonate to release carbon dioxide: Na 2 H 2 P 2 O 7 + NaHCO 3 → Na 3 HP 2 O 7 + CO 2 + H 2 O. It is available in a variety of grades that affect the speed of its action. Because the resulting phosphate residue has an off-taste, SAPP is usually used in very sweet cakes which mask the off-taste. [2]

  8. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    3 + H 2 O + OH − ⇌ H 2 CO 3 + 2 OH − H 2 CO 3 + 2 H 2 O ⇌ HCO − 3 + H 3 O + + H 2 O ⇌ CO 23 + 2 H 3 O +. A bicarbonate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound. Many bicarbonates are soluble in water at standard temperature and pressure; in ...
