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.
