  2. Hydrogen ion - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_ion

    The concentration of hydrogen ions and pH are inversely proportional; in an aqueous solution, an increased concentration of hydrogen ions yields a low pH, and subsequently, an acidic product. By definition, an acid is an ion or molecule that can donate a proton, and when introduced to a solution it will react with water molecules (H 2 O) to ...

  3. Respiratory alkalosis - Wikipedia

    en.wikipedia.org/wiki/Respiratory_alkalosis

    Circulating hydrogen ions and bicarbonate are shifted through the carbonic acid (H 2 CO 3) intermediate to make more CO 2 via the enzyme carbonic anhydrase according to the following reaction: + + + This causes decreased circulating hydrogen ion concentration, and increased pH (alkalosis).

  4. Acidosis - Wikipedia

    en.wikipedia.org/wiki/Acidosis

    Acidosis is a biological process producing hydrogen ions and increasing their concentration in blood or body fluids. pH is the negative log of hydrogen ion concentration and so it is decreased by a process of acidosis.

  5. Lactic acidosis - Wikipedia

    en.wikipedia.org/wiki/Lactic_acidosis

    It increases hydrogen ion concentration tending to the state of acidemia or low pH. The result can be detected with high levels of lactate and low levels of bicarbonate. This is usually considered the result of illness but also results from strenuous exercise. The effect on pH is moderated by the presence of respiratory compensation.

  6. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    He found that it is the intensity of the acid in terms of hydrogen-ion concentration that affects their growth. But existing methods of measuring acidity determined the quantity, not the intensity, of the acid. Next, with his collaborators, Dr. Clark developed accurate methods for measuring hydrogen-ion concentration.

  7. Metabolic alkalosis - Wikipedia

    en.wikipedia.org/wiki/Metabolic_alkalosis

    Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.

  8. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    Most of the carbonic acid then dissociates to bicarbonate and hydrogen ions. The bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper ...

  9. Alkalosis - Wikipedia

    en.wikipedia.org/wiki/Alkalosis

    Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma (alkalemia).In contrast to acidemia (serum pH 7.35 or lower), alkalemia occurs when the serum pH is higher than normal (7.45 or higher).
