Titration definition

tī-trāshən
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.

Titration is a process of figuring out how much of a substance is in a substance with a known volume.

An example of titration is causing a color change in a substance which has been been disolved in a liquid and then calculating the concentration of the substance based on the color.

Titration Sentence Examples

  • The solution is then ready for titration with the standard permanganate solution.

  • Besides the determination of salinity by titration of the chlorides, the method of determination by the specific gravity of the sea-water is still often used.

  • Chlorides can be estimated quantitatively by conversion into silver chloride, or if in the form of alkaline chlorides (in the absence of other metals, and of any free acids) by titration with standard silver nitrate solution, using potassium chromate as an indicator.

  • The reaction of the media must in every case be carefully attended to, a neutral or slightly alkaline reaction being, as a rule, most suitable; for delicate work it may be necessary to standardize the reaction by titration methods.
