The word "titration" is correct in written English.
It is used in chemistry to describe a method for determining the concentration of a substance in a solution. Example: "The students performed a titration to find the exact concentration of the acid in the solution." Alternatives include "quantitative analysis" or "volume analysis."
But as the drip of the titration went up, from 0% to 1% to 2% to 5% and ultimately to 10% of the food being cineole, their behaviour changed.
And a group of researchers led by Carolyn Nersesian of the University of Sydney has just borrowed one of chemistry's most elegant techniques, titration, to answer a pressing ecological question: how do animals choose where to feed Titration, to remind those who dozed through their chemistry lessons, is a way of working out the concentration of a substance in a solution.
The unknown concentration can then be calculated from the amount of known reagent used.In Dr Nersesian's titration the litmus was a species called the brushtail possum.
Electrometric titration makes possible the determination of the approximate number of carboxyl groups, ammonium groups, histidines, and tyrosines per molecule of protein.
The most important titrations based upon complex-formation reactions are those involving the titration of metal ions with the reagent disodium ethylenediaminetetraacetate (a salt of edetic acid, or EDTA).
For the quantitative determination of iodine, one of the following methods may be recommended: (1) gravimetrically, by precipitation as silver iodide; (2) volumetrically, by titrating iodine with a standardized solution of sodium thiosulfate (using starch as an indicator); or (3) potentiometric titration with silver nitrate, which is applicable in the presence of both chloride and bromide.
This signal can be the colour change of an indicator or a change in some electrical property that is measured during the titration.
In the four titrations just mentioned, except coulometric titrations, the end point is indicated by a marked change in the electrical quantity that is being measured.
In coulometric titrations, the quantity of electricity required to carry out a known reaction is measured, and from Faraday's law the quantity of material present is calculated.
Such titrations, classified according to the nature of the chemical reaction occurring between the sample and titrant, include: acid-base titrations, precipitation titrations, complex-formation titrations, and oxidation-reduction (redox) titrations.
Alternatively, for many titrations the end point can be detected by electrical measurements.
