    back titration
    en
    Definition analytical chemistry technique that allows the user to find the concentration of a reactant by reacting it with an excess volume of reactant of known concentration. The resulting mixture is then titrated, taking into account the molarity of the excess that was added Reference "Wikipedia > Back titration. http://en.wikipedia.org/wiki/Back_titration [27.4.2011]"
    Comment This is used as opposed to standard volumetric titration when the substance being analyzed is either too weak to give a valid reaction, or too slow.A back titration is useful if the endpoint of the reverse titration is easier to identify than the endpoint of the normal titration.Back titration is also useful when trying to work out the amount of an acid or base in a non-soluble solid.

Archer and Michael D. Schulz. 'Isothermal titration calorimetry: practical approaches and current applications in soft matter' (24.3.2021). Soft Matter, Issue 38, 2020
    Comment While ITC has primarily been used to investigate the thermodynamics of interactions between biological macromolecules and small molecules, it has become increasingly common for measuring binding interactions between synthetic polymers and small molecules, ions, or nanoparticles.

    Definition The titratable acidity of a solution is an approximation of the solution's total acidity - it is measured by reacting the acids present with a base such as sodium hydroxide(NaOH) to a chosen end point, close to neutrality, as indicated by an acid sensitive colour indicator. Reference "http://www.monashscientific.com.au/TitratableAcidity.htm (6/7/09)"
    Comment "Although not the same thing, total acidity and titratable acidity are sometimes used as synonyms. Total acidity is a more accurate representation of acid concentration than titratable acidity, but is more difficult to measure. Therefore, the easier-to-measure titratable acidity is used to obtain an approximation of a solution's total acidity. (see http://www.monashscientific.com.au/TitratableAcidity.htm (6/7/09)"
