  2. Sodium sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfate

    Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.

  3. Mirabilite - Wikipedia

    en.wikipedia.org/wiki/Mirabilite

    Mirabilite, also known as Glauber's salt, is a hydrous sodium sulfate mineral with the chemical formula Na 2 SO 4 ·10H 2 O. It is a vitreous, colorless to white monoclinic mineral that forms as an evaporite from sodium sulfate-bearing brines. It is found around saline springs and along saline playa lakes.

  5. Sodium salts - Wikipedia

    en.wikipedia.org/wiki/Sodium_salts

    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).

  6. Leblanc process - Wikipedia

    en.wikipedia.org/wiki/Leblanc_process

    The Leblanc process was an early industrial process for making soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate.

  7. Kraft process - Wikipedia

    en.wikipedia.org/wiki/Kraft_process

    [11] [12] During combustion, sodium sulfate is reduced to sodium sulfide by the organic carbon in the mixture: 1. Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. This reaction is similar to thermochemical sulfate reduction in geochemistry. The molten salts ("smelt") from the recovery boiler are dissolved in a process water known as "weak wash".

    Steve is a player character from the 2011 sandbox video game Minecraft.Created by Swedish video game developer Markus "Notch" Persson and introduced in the original 2009 Java-based version, Steve is the first and the original default skin available for players of contemporary versions of Minecraft.

  9. Flue-gas desulfurization - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_desulfurization

    The SO 2 is absorbed in the water, and when oxygen is added reacts to form sulfate ions SO 2− 4 and free H +. The surplus of H + is offset by the carbonates in seawater pushing the carbonate equilibrium to release CO 2 gas: SO 2 + H 2 O + O →H 2 SO 4 HCO − 3 + H + → H 2 O + CO 2. In industry caustic soda (NaOH) is often used to scrub SO ...
