  2. Sodium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bicarbonate

    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

  3. Solvay process - Wikipedia

    en.wikipedia.org/wiki/Solvay_process

    The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [1]

  4. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    The method is appealing to such users because sodium bicarbonate is widely sold as baking soda, and the temperatures required (250 °F (121 °C) to 300 °F (149 °C)) to convert baking soda to sodium carbonate are readily achieved in conventional kitchen ovens. [18]

  5. Sodium percarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_percarbonate

    It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and water-soluble solid. [3] It is sometimes abbreviated as SPC. It contains 32.5% by weight of hydrogen peroxide.

    Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020 [update] , the most expensive non- synthetic element by both mass and volume is rhodium .

  7. Effervescent tablet - Wikipedia

    en.wikipedia.org/wiki/Effervescent_tablet

    The carbon dioxide is generated by a reaction of a compound containing bicarbonate, such as sodium bicarbonate or magnesium bicarbonate, with an acid such as citric acid or tartaric acid. Both compounds are present in the tablet in powder form and start reacting as soon as they dissolve in water. [1] [2] [3] [4]

  8. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    The parameter standard bicarbonate concentration (SBC e) is the bicarbonate concentration in the blood at a P a CO 2 of 40 mmHg (5.33 kPa), full oxygen saturation and 36 °C. [13] Reference ranges for blood tests, comparing blood content of bicarbonate (shown in blue at right) with other constituents.

  9. Carbonate hardness - Wikipedia

    en.wikipedia.org/wiki/Carbonate_hardness

    An aqueous solution containing 120 mg NaHCO 3 (baking soda) per litre of water will contain 1.4285 mmol/l of bicarbonate, since the molar mass of baking soda is 84.007 g/mol. This is equivalent in carbonate hardness to a solution containing 0.71423 mmol/L of (calcium) carbonate, or 71.485 mg/L of calcium carbonate (molar mass 100.09 g/mol).
