  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

  4. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate serves as a flux for silica (SiO 2, melting point 1,713 °C), lowering the melting point of the mixture to something achievable without special materials. This "soda glass" is mildly water-soluble, so some calcium carbonate is added to the melt mixture to make the glass insoluble.

  5. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.

  6. Potassium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Potassium_bicarbonate

    It is manufactured by treating an aqueous solution of potassium carbonate or potassium hydroxide with carbon dioxide: [1] K 2 CO 3 + CO 2 + H 2 O → 2 KHCO 3. Decomposition of the bicarbonate occurs between 100 and 120 °C (212 and 248 °F): 2 KHCO 3 → K 2 CO 3 + CO 2 + H 2 O. This reaction is employed to prepare high purity potassium carbonate.

  7. Salt (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Salt_(chemistry)

    Inorganic compounds with simple ions typically have small ions, and thus have high melting points, so are solids at room temperature. Some substances with larger ions, however, have a melting point below or near room temperature (often defined as up to 100 °C), and are termed ionic liquids. [64]

  8. Sodium - Wikipedia

    en.wikipedia.org/wiki/Sodium

    Sodium is now produced commercially through the electrolysis of molten sodium chloride (common salt), based on a process patented in 1924. [64] [65] This is done in a Downs cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. [66]

  9. Sodium silicate - Wikipedia

    en.wikipedia.org/wiki/Sodium_silicate

    Sodium silicates can also be obtained by dissolving silica SiO 2 (whose melting point is 1713 °C) in molten sodium carbonate (that melts with decomposition at 851 °C): [17] x Na 2 CO 3 + SiO 2 → (Na 2 O) x · SiO 2 + CO 2. The material can be obtained also from sodium sulfate (melting point 884 °C) with carbon as a reducing agent: 2x Na 2 ...
