Definition of TITRATION
: a method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution
: a method or the process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution; especially: the analytical process of successively adding from a burette measured amounts of a reagent to a known volume of a sample in solution or a known weight of a sample until a desired end point (as a color change) is reached
Process of chemical analysis in which the quantity of some constituent of a dissolved sample is determined by adding an exactly measured quantity of another dissolved substance with which it reacts in a definite, known proportion. The solution of known concentration is gradually added to the unknown solution from a burette (a long measuring tube with a valve at the bottom) until the equivalence point (end point) is reached. The amount of the unknown substance can then be calculated. The equivalence point is determined by a detectable change, for instance, of colour in an indicator substance (e.g., litmus) or in an electrical property. Reactions used in titration include acid-base reactions, precipitations (seesolution), formation of complexes, and oxidation-reduction reactions. See alsopH.
