  2. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Water purification is the process of removing undesirable chemicals, ... or sodium hydroxide can be added to raise the pH during water purification processes. Lime ...

  3. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide is sometimes used during water purification to raise the pH of water supplies. Increased pH makes the water less corrosive to plumbing and reduces the amount of lead, copper and other toxic metals that can dissolve into drinking water.

  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. Ion exchange - Wikipedia

    en.wikipedia.org/wiki/Ion_exchange

    Ion exchange is widely used in the food and beverage industry, hydrometallurgy, metals finishing, chemical, petrochemical, pharmaceutical technology, sugar and sweetener production, ground- and potable-water treatment, nuclear, softening, industrial water treatment, semiconductor, power, and many other industries. [citation needed]

  6. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Pure water has a charge carrier density similar to semiconductors [12] [page needed] since it has a low autoionization, K w = 1.0×10 −14 at room temperature and thus pure water conducts current poorly, 0.055 μS/cm. [13] Unless a large potential is applied to increase the autoionization of water, electrolysis of pure water proceeds slowly ...

  7. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    The mercury is the cathode, where sodium is produced and forms an amalgam with the mercury. The amalgam is continuously drawn out of the cell and reacted with water which decomposes the amalgam into sodium hydroxide, hydrogen and mercury. The mercury is recycled into the electrolytic cell. Chlorine is produced at the anode and bubbles out of ...

  8. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    A study found the mean concentration of sodium in softened water to be 278 mg/L. [23] In 2 liters of water—the amount of drinking water typically suggested for an average adult, this constitutes about 22% of the recommended sodium intake by the US CDC and may make a difference to those who need to significantly limit their sodium consumption.

  9. Purified water - Wikipedia

    en.wikipedia.org/wiki/Purified_water

    Processes rendering water potable but not necessarily closer to being pure H 2 O / hydroxide + hydronium ions include the use of dilute sodium hypochlorite, ozone, mixed-oxidants (electro-catalyzed H 2 O + NaCl), and iodine; See discussion regarding potable water treatments under "Health effects" below.
