Questions and Answers
Explain the purpose of titration in quantitative chemical analysis.
Titration is used to determine the concentration of an identified analyte in a solution by reacting it with a standard solution of known concentration and volume.
What is the role of the titrant in a titration process?
The titrant is the reagent of known concentration and volume that reacts with the analyte to determine its concentration.
From where does the word 'titration' descend and what did it originally mean?
The word 'titration' descends from the French word 'titrer', which originally meant the proportion of gold or silver in coins or works of gold or silver.

Study Notes
Titration in Quantitative Chemical Analysis
- Titration is a laboratory technique used to determine the exact amount of a substance (analyte) in a sample by reacting it with a known amount of another substance (titrant) of known concentration.
Role of the Titrant
- The titrant is a solution of known concentration that reacts with the analyte in a one-to-one stoichiometric ratio.
- The titrant is added to the analyte until the reaction is complete, and the amount of titrant used is used to calculate the amount of analyte present.
Origin of the Word 'Titration'
- The word 'titration' descends from the Latin 'titulus', meaning 'inscription' or 'label'.
- Originally, the word 'titration' referred to the act of labeling or inscribing the content of a container.
Evolution of the Word 'Titre'
- The French chemist Karl Friedrich Mohr was the first to use 'titre' as a verb, meaning 'to determine the concentration of a solution'.
- Over time, the word 'titre' evolved to mean the concentration of a solution, and eventually, the entire process of determining the concentration of a solution through the addition of a known amount of another substance.
