  2. Citric acid - Wikipedia

    en.wikipedia.org/wiki/Citric_acid

    Citric acid is an excellent chelating agent, binding metals by making them soluble. It is used to remove and discourage the buildup of limescale from boilers and evaporators. [ 15 ] It can be used to treat water, which makes it useful in improving the effectiveness of soaps and laundry detergents.

    en.wikipedia.org/wiki/Chelation

    A chelating agent is the main component of some rust removal formulations. Citric acid is used to soften water in soaps and laundry detergents. A common synthetic chelator is EDTA. Phosphonates are also well-known chelating agents. Chelators are used in water treatment programs and specifically in steam engineering.

    According to Ulrich Schmidt [8] and others, plants' concentration of uranium is considerably increased by an application of citric acid, which solubilizes the uranium (and other metals). Radionuclides : Cs-137 and Sr-90 are not removed from the top 0.4 meters of soil even under high rainfall, and migration rate from the top few centimeters of ...

    A process related to the sol-gel route is the Pechini, or liquid mix, process (named after its American inventor, Maggio Pechini). An aqueous solution of suitable oxides or salts is mixed with an alpha hydroxycarboxylic acid such as citric acid.

  7. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Rain water contains dissolved carbon dioxide taken from the atmosphere. Some of the dissolved carbon dioxide reacts with the water to form carbonic acid, which remains in solution. Minerals containing calcium and magnesium form soluble bicarbonates when exposed to carbonic acid. Water containing these minerals is known as "hard water".

    It is a colorless weak organic acid. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. More than two million tons of citric acid are manufactured every year. It is used widely as acidifier, flavoring, preservative, and chelating agent.
