titration

British  

/ taɪˈtreɪʃən /

noun

1. an operation, used in volumetric analysis, in which a measured amount of one solution is added to a known quantity of another solution until the reaction between the two is complete. If the concentration of one solution is known, that of the other can be calculated

titration Scientific  

/ tī-trā′shən /

1. The process or operation of determining the concentration of a substance in solution. Titration is performed by adding to a known volume of the solution a standard reagent of known concentration in carefully measured amounts until a reaction of definite and known proportion is completed (as shown by a color change or by electrical measurement) and then calculating the unknown concentration.
