  2. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...

  3. Lye - Wikipedia

    en.wikipedia.org/wiki/Lye

    Potassium hydroxide soaps are softer and more easily dissolved in water than sodium hydroxide soaps. Sodium hydroxide and potassium hydroxide are not interchangeable in either the proportions required or the properties produced in making soaps. [citation needed] "Hot process" soap making also uses lye as the main ingredient. Lye is added to ...

  4. Electrolysed water - Wikipedia

    en.wikipedia.org/wiki/Electrolysed_water

    This "acidic electrolyzed water" can be raised in pH by mixing in the desired amount of hydroxide ion solution from the cathode compartment, yielding a solution of Hypochlorous acid (HOCl) and sodium hydroxide (NaOH). A solution whose pH is 7.3 will contain equal concentrations of hypochlorous acid and hypochlorite ion; reducing the pH will ...

  5. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  6. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    When all the available Na + ions have been replaced with calcium or magnesium ions, the resin must be recharged by eluting the Ca 2+ and Mg 2+ ions using a solution of sodium chloride or sodium hydroxide, depending on the type of resin used. [9] For anionic resins, regeneration typically uses a solution of sodium hydroxide or

    Along with the antiperspirant, there are two aluminum-free options: the Sport deodorant stick - made with sodium stearate - and the Natural deodorant stick, which contains sodium hydroxide and a ...

  8. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    In the case of water electrolysis, Gibbs free energy represents the minimum work necessary for the reaction to proceed, and the reaction enthalpy is the amount of energy (both work and heat) that has to be provided so the reaction products are at the same temperature as the reactant (i.e. standard temperature for the values given above ...
