Sign in to savethumb|A burette and [[Erlenmeyer flask (conical flask) being used for an acid–base titration.]] Titration (also known as titrimetry and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). A reagent, termed the titrant or titrator, is prepared as a standard solution of known concentration and volume. The titrant reacts with a solution of analyte (which may also be termed the titrand) to determine the analyte's concentration. The volume of titrant that reacted with the analyte i
AI overview
Titration is a laboratory technique used to determine how much of a particular substance is present in a solution by adding a reagent of known strength until a reaction is complete. By measuring the volume of reagent needed to finish the reaction, scientists can calculate the concentration of the substance being tested.

==History and etymology== The word "titration" descends from the French word tiltre (1543), meaning the proportion of gold or silver in coins or in works of gold or silver; i.e., a measure of fineness or purity. Tiltre became titre, which thus came to mean the "fineness of alloyed gold", and then the "concentration of a substance in a given sample". In 1828, the French chemist Joseph Louis Gay-Lussac first used titre as a verb (titrer), meaning "to determine the concentration of a substance in a given sample".
