volumetric analysis
Definition
- Noun:
- Quantitative chemical analysis by measuring volumes: A method in analytical chemistry where the concentration of a substance in a solution is determined by measuring the volume of a standard reagent solution of known concentration required to react completely with it.
- Measurement of gas volumes: The determination of the volume of gases, or the changes in their volume, during a chemical reaction or physical process.
Usage Examples
- Noun:
- In the laboratory, we used volumetric analysis to determine the acidity of the vinegar sample.
- The classic titration experiment is a fundamental technique in volumetric analysis.
- Early chemists employed volumetric analysis to study the combining volumes of gases like hydrogen and oxygen.
Advanced Usage
- Titrimetric analysis is often used synonymously with the first meaning of volumetric analysis, emphasizing the titration process.
- The principle of volumetric analysis relies on precise measurement using specialized glassware like burettes, pipettes, and volumetric flasks.
Variants and Related Words
- Titration (n): The core experimental procedure in volumetric analysis where a solution is added from a burette to another solution until the reaction is complete.
- Titrant (n): The standard solution of known concentration used in a titration.
- Analyte (n): The substance whose concentration is being determined in the analysis.
Synonyms
- For the first meaning: Titrimetry, quantitative analysis by titration.
- For the second meaning: Gas volumetry, manometric measurement.
Related Phrases and Concepts
- Endpoint / Equivalence point: The point in a titration at which the reaction is complete, often indicated by a color change.
- Standard solution: A reagent solution of precisely known concentration, essential for volumetric analysis.
Noun
-
quantitative analysis by the use of definite volumes of standard solutions or reagents
-
determination of the volume of gases (or changes in their volume) during combination
