titration

The process, operation, or method of determining the concentration of a substance in solution by adding to it a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed, usually as shown by a color change or by electrical measurement, and then calculating the unknown concentration.

In analytical chem., a process for ascertaining the quantity of any given constituent present in a compound by observing the quantity of a liquid of known strength (called a standard solution) necessary to convert the constituent into another form, the close of the reaction being marked by some definite phenomenon, usually a change of color or the formation of a precipitate. Also called volumetric analysis.

The act or process of titrating; a substance obtained by titrating.

The determination of the concentration of some substance in a solution by slowly adding measured amounts of some other substance (normally using a burette) until a reaction is shown to be complete, for instance by the colour change of an indicator.

a measured amount of a solution of unknown concentration is added to a known volume of a second solution until the reaction between them is just complete; the concentration of the unknown solution (the titer) can then be calculated
