  2. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acidbase_titration

    Acidbase titration is also utilized in the analysis of acid rain effects on soil and water bodies, contributing to the overall understanding and management of environmental quality. [24] The method's prevision and reliability make it a valuable tool in safeguarding ecosystems and assessing the impact of human activities on natural water ...

  3. Titration - Wikipedia

    en.wikipedia.org/wiki/Titration

    Acidbase titrations depend on the neutralization between an acid and a base when mixed in solution. In addition to the sample, an appropriate pH indicator is added to the titration chamber, representing the pH range of the equivalence point. The acidbase indicator indicates the endpoint of the titration by changing color.

  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. 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 ,

  6. Thermometric titration - Wikipedia

    en.wikipedia.org/wiki/Thermometric_titration

    Non-aqueous acidbase titrations can be carried out advantageously by thermometric means. Acid leach solutions from some copper mines can contain large quantities of Fe(III) as well as Cu(II). The "free acid" (sulfuric acid) content of these leach solutions is a critical process parameter. While thermometric titrimetry can determine the free ...

  7. 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).

  8. Neutralization (chemistry) - Wikipedia

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

    Animation of a strong acid–strong 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 ...

  9. 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 ...
