Examples of titrant in the following topics:

  • Redox Titrations

    • As with acid-base titrations, a redox titration (also called an oxidation-reduction titration) can accurately determine the concentration of an unknown analyte by measuring it against a standardized titrant.
    • In this case, the use of KMnO4 as a titrant is particularly useful, because it can act as its own indicator; this is due to the fact that the KMnO4 solution is bright purple, while the Fe2+ solution is colorless.
    • A student conducts the redox titration and reaches the endpoint after adding 25 mL of the titrant.
    • For example, wines can be analyzed for sulfur dioxide using a standardized iodine solution as the titrant.
    • A redox titration using potassium permanganate as the titrant.
  • Strong Acid-Weak Base Titrations

    • A small amount of the acid solution of known concentration is placed in the burette (this solution is called the titrant).
    • A known volume of base with unknown concentration is placed into an Erlenmeyer flask (the analyte), and, if pH measurements can be obtained via electrode, a graph of pH vs. volume of titrant can be made (titration curve).
    • Recall that strong acid-weak base titrations can be performed with either serving as the titrant.
  • Acid-Base Titrations

    • titrant (a standard solution of known concentration; a common example is aqueous sodium carbonate)
    • (Subtracting the initial volume from the final volume will yield the amount of titrant used to reach the endpoint.)
    • Compute the concentration of an unknown acid or base given its volume and the volume and concentration of the standardized titrant.
  • Strong Acid-Strong Base Titrations

    • It is known as the titrant.
  • Diprotic and Polyprotic Acids

    • Diprotic and polyprotic acids show unique profiles in titration experiments, where a pH versus titrant volume curve clearly shows two equivalence points for the acid; this is because the two ionizing hydrogens do not dissociate from the acid at the same time.
