  2. Hydronium - Wikipedia

    en.wikipedia.org/wiki/Hydronium

    In pure water, there is an equal number of hydroxide and H + ions, so it is a neutral solution. At 25 °C (77 °F), pure water has a pH of 7 and a pOH of 7 (this varies when the temperature changes: see self-ionization of water). A pH value less than 7 indicates an acidic solution, and a pH value more than 7 indicates a basic solution. [7]

  3. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    The smaller the difference, the more the overlap. In the case of citric acid, the overlap is extensive and solutions of citric acid are buffered over the whole range of pH 2.5 to 7.5. Calculation of the pH with a polyprotic acid requires a speciation calculation to be performed. In the case of citric acid, this entails the solution of the two ...

  4. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    Solutions with a pH of 7 at 25 °C are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water). The neutral value of the pH depends on the temperature and is lower than 7 if the temperature increases above 25 °C. The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very ...

  5. Phosphate-buffered saline - Wikipedia

    en.wikipedia.org/wiki/Phosphate-buffered_saline

    Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH.

  6. Henderson–Hasselbalch equation - Wikipedia

    en.wikipedia.org/wiki/Henderson–Hasselbalch...

    The Henderson–Hasselbalch equation can be used to model these equilibria. It is important to maintain this pH of 7.4 to ensure enzymes are able to work optimally. [10] Life threatening Acidosis (a low blood pH resulting in nausea, headaches, and even coma, and convulsions) is due to a lack of functioning of enzymes at a low pH. [10]

    The verdict when it comes to if Gatorade is hydrating is this: It absolutely does hydrate the body and can even do so more effectively than water. But that doesn’t mean you should drink it ...

  9. Intracellular pH - Wikipedia

    en.wikipedia.org/wiki/Intracellular_pH

    Physiologically normal intracellular pH is most commonly between 7.0 and 7.4, though there is variability between tissues (e.g., mammalian skeletal muscle tends to have a pH i of 6.8–7.1). [4] [5] There is also pH variation across different organelles, which can span from around 4.5 to 8.0. [6] [7] pH i can be measured in a number of ...
