  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. 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 ...

    This is suitable for all acidbase equilibria. log 10 β values between about 2 and 11 can be measured directly by potentiometric titration using a glass electrode . This enormous range of stability constant values (ca. 100 to 10 11 ) is possible because of the logarithmic response of the electrode.

  6. 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 ,

    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.

  9. 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.
