  2. Water intoxication - Wikipedia

    en.wikipedia.org/wiki/Water_intoxication

    Water intoxication, also known as water poisoning, hyperhydration, overhydration, or water toxemia, is a potentially fatal disturbance in brain functions that can result when the normal balance of electrolytes in the body is pushed outside safe limits by excessive water intake. Under normal circumstances, accidentally consuming too much water ...

  3. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. [4]

  4. Alkalinity - Wikipedia

    en.wikipedia.org/wiki/Alkalinity

    Total alkalinity is not (much) affected by temperature, pressure, or pH, and is thus itself a conservative measurement, which increases its usefulness in aquatic systems. All anions except HCO − 3 and CO 2− 3 have low concentrations in Earth's surface water (streams, rivers, and lakes). Thus carbonate alkalinity, which is equal to [HCO − ...

  5. Electrolysed water - Wikipedia

    en.wikipedia.org/wiki/Electrolysed_water

    An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride. [1]

  6. Freshwater acidification - Wikipedia

    en.wikipedia.org/wiki/Freshwater_acidification

    Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake. [1] Freshwater acidification is primarily caused by sulfur oxides (SO x) and nitrogen oxides (NO x) entering ...

  7. Heavy water - Wikipedia

    en.wikipedia.org/wiki/Heavy_water

    The electrode correction for alkaline conditions is 0.456 for heavy water. The alkaline correction is then pD+ = pH a (apparent reading from pH meter) + 0.456. These corrections are slightly different from the differences in p[D+] and p[OD-] of 0.44 from the corresponding ones in heavy water. [16]

  8. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Water-reactive substances. Water-reactive substances[1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium.

  9. Alkaline water electrolysis - Wikipedia

    en.wikipedia.org/wiki/Alkaline_water_electrolysis

    20-30 years [4] Alkaline water electrolysis is a type of electrolysis that is characterized by having two electrodes operating in a liquid alkaline electrolyte. Commonly, a solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) at 25-40 wt% is used. [6] These electrodes are separated by a diaphragm, separating the product gases and ...
