titration ti·tra·tion (tī-trā'shən)
n.
The process, operation, or method of determining the concentration of a substance in a solution to which the addition of a reagent having a known concentration is made 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.
| titration (tī-trā'shən) Pronunciation Key
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. |
In chemistry, the determination of what materials are present in a sample by adding precise amounts of known chemicals and observing the chemical reaction.
Note: The term titration is occasionally used informally to suggest extreme precision in some sort of measurement or determination.
