  2. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acidbase_titration

    Note that when an acid neutralizes a base, the pH may or may not be neutral (pH = 7). The pH depends on the strengths of the acid and base. In the case of a weak acid and strong base titration, the pH is greater than 7 at the equivalence point. Thus pH can be calculated using the following formula: [1]

  3. Gran plot - Wikipedia

    en.wikipedia.org/wiki/Gran_plot

    For a strong acid-strong base titration monitored by pH, we have at any i'th point in the titration = [+] [] where K w is the water autoprotolysis constant.. If titrating an acid of initial volume and concentration [+] with base of concentration [], then at any i'th point in the titration with titrant volume ,

  4. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    A titration curve is a curve in graph the x-coordinate of which represents the volume of titrant added since the beginning of the titration, and the y-coordinate of which represents the concentration of the analyte at the corresponding stage of the titration (in an acidbase titration, the y-coordinate usually represents the pH of the solution).

  5. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    Likewise, any aqueous base with an association constant pK b less than about 0, corresponding to pK a greater than about 14, is leveled to OH − and is considered a strong base. [22] Nitric acid, with a pK value of around −1.7, behaves as a strong acid in aqueous solutions with a pH greater than 1. [23] At lower pH values it behaves as a ...

  6. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    Animation of a strong acidstrong base neutralization titration (using phenolphthalein). The equivalence point is marked in red. In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other. In a reaction in water, neutralization ...

    When the electrode is calibrated with solutions of known concentration, by means of a strong acidstrong base titration, for example, a modified Nernst equation is assumed. = + ⁡ [] where s is an empirical slope factor.

  8. Titration curve - Wikipedia

    en.wikipedia.org/wiki/Titration_curve

    A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...

    Peter Arthur Robert Stewart (1921–1993) was a Canadian physiologist who introduced an alternate approach to understanding acidbase physiology.. He outlined his model in a paper in 1978, [1] and explained it his 1981 book, How to Understand AcidBase. [2]
