The word "titration" comes from the [[Latin]] word titulus, [[meaning]] inscription or title. The French word ''titre'', also from this origin, means rank.

Volumetric analysis originated in late 18th-century France. [http://en.wikipedia.org/wiki/Fran%C3%A7ois-Antoine-Henri_Descroizilles François-Antoine-Henri Descroizilles] (fr) developed the first burette (which was similar to a graduated cylinder) in 1791. [http://en.wikipedia.org/wiki/Joseph_Louis_Gay-Lussac Joseph Louis Gay-Lussac] developed an improved version of the burette that included a side arm, and coined the terms "[http://en.wikipedia.org/wiki/Pipette pipette]" and "[http://en.wikipedia.org/wiki/Burette burette]" in an 1824 paper on the standardization of indigo solutions. A major breakthrough in the methodology and popularization of volumetric analysis was due to [http://en.wikipedia.org/wiki/Karl_Friedrich_Mohr Karl Friedrich Mohr], who redesigned the burette by placing a clamp and a tip at the bottom, and wrote the first textbook on the topic, ''Lehrbuch der chemisch-analytischen Titrirmethode (Textbook of analytical-chemical titration methods)'', published in 1855.

==Description==

'''Titration''', also known as ''titrimetry'', is a common [[laboratory]] [[method]] of [http://en.wikipedia.org/wiki/Quantitative_research quantitative chemical analysis] that is used to determine the unknown [[concentration]] of an identified [http://en.wikipedia.org/wiki/Analyte analyte]. Since volume measurements play a key role in ''titration'', it is also known as volumetric analysis. A [http://en.wikipedia.org/wiki/Reagent reagent], called the ''titrant'' or ''titrator'' is prepared as a standard solution. A known concentration and volume of ''titrant'' [[reacts]] with a solution of analyte or titrand to determine concentration.

A typical ''titration'' begins with a beaker or [http://en.wikipedia.org/wiki/Erlenmeyer_flask Erlenmeyer flask] containing a very precise volume of the analyte and a small amount of indicator placed underneath a calibrated [http://en.wikipedia.org/wiki/Burette burette] or [http://en.wikipedia.org/wiki/Pipette chemistry pipetting syringe] containing the titrant. Small volumes of the titrant are then added to the analyte and indicator until the indicator changes, reflecting arrival at the [http://en.wikipedia.org/wiki/Equivalence_point endpoint] of the titration. Depending on the endpoint desired, single drops or less than a single drop of the titrant can make the [[difference]] between a permanent and temporary [[change]] in the indicator. When the endpoint of the reaction is reached, the volume of reactant consumed is measured and used to calculate the [[concentration]] of analyte.[http://en.wikipedia.org/wiki/Titration]
