alkalimeter

A scientist uses an alkalimeter to measure the pH of a solution.

Definition

1. Noun:
   • A chemical instrument: An "alkalimeter" is an apparatus or device used to measure the concentration of alkali in a solution, typically by titration.
   • A measurement tool: In analytical chemistry, it refers specifically to a graduated tube or burette used in alkalimetry (the process of determining the strength of an alkaline substance).

Usage Examples

• Noun:
  • The chemist used an alkalimeter to determine the exact alkalinity of the water sample. (The device measured the alkali concentration.)
  • Before the titration began, she carefully filled the alkalimeter with the acid solution. (The graduated tube was prepared for measurement.)

Advanced Usage

• "to calibrate an alkalimeter": to adjust the instrument to ensure accurate measurements.

  • The laboratory technician had to calibrate the alkalimeter before each use. (The device was set to a standard for precision.)

• "alkalimeter reading": the numerical value obtained from the instrument.

  • The alkalimeter reading indicated a high level of sodium hydroxide in the mixture. (The measurement result showed strong alkalinity.)

Variants and Related Words

• Alkalimetry (n): the scientific method or process of measuring the concentration of alkalis.

  • Alkalimetry is a common technique in acid-base titration experiments. (The process of measuring alkali strength.)

• Alkalimetric (adj): relating to or involving the measurement of alkalis.

  • The alkalimetric analysis confirmed the sample's purity. (The measurement-based assessment.)

Synonyms

• Burette: a graduated glass tube with a tap, used for dispensing measured amounts of liquid in titration.
• Titration apparatus: a general term for equipment used in titration, including an alkalimeter.
