Definition

Noun: A eudiometer is a scientific instrument used in chemistry, specifically a graduated glass tube, designed to measure changes in gas volume that occur during chemical reactions between gases.

Usage

The word eudiometer is a technical, scientific term. It is used almost exclusively in laboratory and academic contexts related to chemistry and gas analysis. * It functions as a countable noun (e.g., a eudiometer, several eudiometers). * It is typically preceded by articles (a, the) or other determiners.

Examples

• The chemist used a eudiometer to measure the volume of hydrogen gas produced in the reaction.
• Accurate readings from the eudiometer are crucial for calculating the stoichiometry of the gaseous reaction.
• In the 18th century, the eudiometer was an important tool for studying the composition of air.

Advanced Usage

• Eudiometric analysis: This phrase refers to the quantitative analysis of gases using a eudiometer.
  • Eudiometric analysis was employed to determine the oxygen content of the sample.

Variants and Related Words

• Eudiometric (adjective): Pertaining to or involving a eudiometer or eudiometry.
  • The eudiometric data confirmed the hypothesis.
• Eudiometry (noun): The measurement or analysis of gases, especially using a eudiometer.
  • His research focused on the history of eudiometry.

Synonyms

• Gas-measuring tube
• Gas burette (Note: A gas burette is a similar but not always identical piece of apparatus.)

Different Meanings
