  2. 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 ...

  3. 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 ...

  4. Electrolysed water - Wikipedia

    en.wikipedia.org/wiki/Electrolysed_water

    Both sodium hydroxide and hypochlorous acid are efficient disinfecting agents; [1] [4] as mentioned above, the key to effective sanitation is to have a high proportion of hypochlorous acid present, this happens between acidic and neutral pH conditions. [3] EOW will kill spores and many viruses and bacteria. [3]

  5. Water chlorination - Wikipedia

    en.wikipedia.org/wiki/Water_chlorination

    Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. This method is used to kill bacteria, viruses and other microbes in water.

  6. Insecticidal soap - Wikipedia

    en.wikipedia.org/wiki/Insecticidal_soap

    Insecticidal soap is used to control many plant insect pests. Soap has been used for more than 200 years as an insect control. [1] Because insecticidal soap works on direct contact with pests via the disruption of cell membranes when the insect is penetrated with fatty acids, the insect's cells leak their contents causing the insect to dehydrate and die. [2]

  7. Ferric chloride test - Wikipedia

    en.wikipedia.org/wiki/Ferric_chloride_test

    The sample is dissolved in water, or a mixture of water and ethanol, and a few drops of neutral ferric chloride (FeCl 3) solution, which is prepared by adding de-ionised water. Add sodium hydroxide to the mixture until a permanent brown precipitate is formed. The formation of a red, blue, green, or purple coloration indicates the presence of ...

  8. Hydrolysis - Wikipedia

    en.wikipedia.org/wiki/Hydrolysis

    For example, sodium acetate dissociates in water into sodium and acetate ions. Sodium ions react very little with the hydroxide ions whereas the acetate ions combine with hydronium ions to produce acetic acid. In this case the net result is a relative excess of hydroxide ions, yielding a basic solution. Strong acids also undergo hydrolysis.

  9. Bittern (salt) - Wikipedia

    en.wikipedia.org/wiki/Bittern_(salt)

    Magnesium hydroxide (Mg(OH) 2) can be derived from bittern. [4] Adding an alkaline solution such as sodium hydroxide (NaOH) or lime will cause magnesium hydroxide to precipitate, although lime is not as effective. Slower addition of the alkaline solution results in the precipitation of larger particles that are easier to remove from solution.
