What does volumetry mean?
Volumetry is the measurement of volume, especially as a method of quantitative chemical analysis. In this context, the quantity of a solution or reagent is measured as a reagent reacts with an analyte, allowing a laboratory to determine its concentration, purity, or other properties. The technique is closely associated with titration and related forms of volumetric analysis. Its name reflects its dependence on precisely measured volumes, so accurate glassware, controlled conditions, and careful technique are important. Although the word has a broad literal meaning, it is most commonly encountered in scientific and technical writing. For many general readers, volumetric analysis or titration may be more immediately familiar than volumetry itself. The term is nevertheless useful because it names both the underlying principle and the analytical practice of obtaining chemical information through volume measurements.
nounThe measurement of volume. In analytical chemistry, it refers especially to quantitative analysis based on measuring the volume of a solution or reagent.
- The measurement or determination of volume.
- Quantitative chemical analysis performed by measuring the volumes of solutions or reagents.
"The laboratory used volumetry to determine the concentration of the titrant."
"The laboratory used volumetry to determine the concentration of the titrant."
"The technique relies on carefully measuring the volumes of solutions during the reaction."
The regular plural is volumetries, although it is uncommon because volumetry is normally used as an uncounted name for a method or field.
"The two volumetries produced consistent measurements."
Volumetry turns the volume of a solution into evidence of what it contains.

Where does volumetry come from?
The English word comes through French volumétrie, formed from volume and the metric element -métrie. Its deeper root is Latin volumen, meaning a volume, roll, or mass, which also underlies words such as volume, volumetric, and voluminous. In English, volumetry developed especially as a technical term associated with measurement and chemical analysis.
How volumetry is actually used
Volumetry is a specialized term, used most often in analytical chemistry and related laboratory science. It is less common in general prose than the broader expression volumetric analysis.
Easily confused with volumetry
Volumetry is the noun naming the measurement of volume, while volumetric is chiefly an adjective describing something involving or measured by volume.
