Definition
- Noun:
- Volumetric analysis using standard solutions of alkali to measure the amount of acid present: A chemical analytical technique where the concentration of an acid in a solution is determined by measuring the volume of a standard alkali solution of known concentration required to neutralize it.
Usage
- Alkalimetry is a specific type of titration. It is the counterpart to acidimetry.
- The word is used in scientific, chemical, and analytical contexts.
- It is typically an uncountable noun referring to the technique or process.
Examples
- The laboratory technician performed alkalimetry to determine the acetic acid content in the vinegar sample.
- Alkalimetry is a fundamental technique taught in quantitative analytical chemistry courses.
- The results of the alkalimetry indicated a high concentration of hydrochloric acid in the solution.
Advanced Usage
- The process and calculations in alkalimetry are based on the chemical principle of neutralization: .
- The endpoint of an alkalimetric titration is often detected using an indicator like phenolphthalein, which changes color when the solution becomes basic.
Variants and Related Words
- Alkalimetric (adjective): Relating to or involving alkalimetry.
- The alkalimetric titration was performed with great precision.
- Alkalimeter (noun): An apparatus or instrument used for alkalimetry (though "burette" is the more common specific tool).
Synonyms
- Alkali titration: A more descriptive synonym.
- Neutralization titration (using a standard base): A broader term that encompasses alkalimetry.
Related Terms (Not Synonyms)
- Acidimetry: The complementary technique using a standard acid to measure an alkali.
- Titration: The general volumetric analytical method to which alkalimetry belongs.
