  2. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acidbase_titration

    An acidbase titration is a method of quantitative analysis for determining the concentration of Brønsted-Lowry acid or base (titrate) by neutralizing it using a solution of known concentration (titrant). [1] A pH indicator is used to monitor the progress of the acidbase reaction and a titration curve can be constructed. [1]

  3. 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).

  4. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acidbase_reaction

    In chemistry, an acidbase reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acidbase theories, for example, Brønsted–Lowry acidbase theory.

  5. pH indicator - Wikipedia

    en.wikipedia.org/wiki/PH_indicator

    For example, if the concentration of the conjugate base is 10 times greater than the concentration of the acid, their ratio is 10:1, and consequently the pH is pK a + 1 or pK b + 1. Conversely, if a 10-fold excess of the acid occurs with respect to the base, the ratio is 1:10 and the pH is pK a − 1 or pK b − 1.

    Most familiar to those who have taken chemistry during secondary education is the acid-base titration involving a color-changing indicator, such as phenolphthalein. There are many other types of titrations, for example, potentiometric titrations or precipitation titrations.

  7. Kjeldahl method - Wikipedia

    en.wikipedia.org/wiki/Kjeldahl_method

    If boric acid (or some other weak acid) was used, direct acidbase titration is done with a strong acid of known concentration. HCl or H 2 SO 4 can be used. Indirect back titration is used instead if strong acids were used to make the standard acid solution: strong base of known concentration (like NaOH) is used to neutralize the solution. In ...

  8. 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 ,

  9. Potentiometric titration - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_titration

    Thus the potentiometric titration involve measurement of E cell with the addition of titrant. Types of potentiometric titration include acidbase titration (total alkalinity and total acidity), redox titration (HI/HY and cerate), precipitation titration (halides), and complexometric titration (free EDTA and Antical #5).
