  2. Lime softening - Wikipedia

    en.wikipedia.org/wiki/Lime_softening

    Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process) [1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation.

  3. Soda lime - Wikipedia

    en.wikipedia.org/wiki/Soda_lime

    Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.

  4. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Lime softening is the process in which lime is added to hard water to make it softer. It has several advantages [ further explanation needed ] over the ion-exchange method but is mainly suited to commercial treatment applications.

  5. Calcium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_hydroxide

    Calcium hydroxide has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide.

  6. Soda–lime glass - Wikipedia

    en.wikipedia.org/wiki/Sodalime_glass

    The manufacturing process for soda–lime glass consists in melting the raw materials, which are the silica, soda, lime (in the form of Ca(OH) 2), dolomite (CaMg(CO 3) 2, which provides the magnesium oxide), and aluminium oxide; along with small quantities of fining agents (e.g., sodium sulfate (Na 2 SO 4), sodium chloride (NaCl), etc.) in a glass furnace at temperatures locally up to 1675 °C ...

  7. Residual sodium carbonate index - Wikipedia

    en.wikipedia.org/wiki/Residual_Sodium_Carbonate...

    To avoid scaling in water cooled heat exchangers, water is treated by lime and or soda ash to remove the water hardness. The following chemical reactions take place in lime soda softening process which precipitates the calcium and magnesium salts as calcium carbonate and magnesium hydroxide which have very low solubility in water.

  8. Lime (material) - Wikipedia

    en.wikipedia.org/wiki/Lime_(material)

    Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1] The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. [2]

  9. Limeade - Wikipedia

    en.wikipedia.org/wiki/Limeade

    Limeade, also called lime soda, is a lime-flavored, sometimes carbonated, drink. It is usually sweetened with sugar or sweeteners . A common method of preparation is to juice limes and combine the juice with simple syrup or honey syrup, along with some water and perhaps more sugar or honey. [ 1 ]
