Definition
Noun: - A method of quantitative chemical analysis based on the measurement of mass: Gravimetric analysis is a technique in analytical chemistry where the amount of an analyte (the substance being measured) is determined by isolating it as a pure, weighable compound and measuring its mass.
Usage
This term is used specifically in scientific and chemical contexts to describe a precise analytical procedure. - The purity of the ore sample was determined through gravimetric analysis. - Gravimetric analysis is often considered a classical and highly accurate method for determining the concentration of an ion in a solution.
Advanced Usage
- "to perform a gravimetric analysis": to carry out this specific analytical procedure.
- The laboratory technician will perform a gravimetric analysis on the precipitate to calculate the chloride content.
Variants and Related Words
- Gravimetric (adjective): Pertaining to measurement by weight.
- The gravimetric method yielded more reliable data than the volumetric one.
- Analyte (noun): The substance whose chemical constituents are being identified and measured.
- Precipitate (noun/verb): In this context, the solid compound isolated from a solution for weighing.
Synonyms
- Quantitative analysis by weight: This is a direct descriptive synonym.
- Gravimetry: While often used interchangeably with gravimetric analysis, gravimetry can more broadly refer to the science of measurement of weight.
Related Phrases
- Gravimetric factor: A calculated ratio used to convert the mass of a weighed compound to the mass of the desired analyte.
- Accurate results depend on using the correct gravimetric factor.
