In a volumetric titration, what is the analyte?

• A. The species in the sample whose amount or concentration is being determined
• B. The solvent used to dissolve the sample and reagents (the diluent)
• C. The standard solution of known concentration added from the buret (the titrant)
• D. A compound added to signal the end point by a color change (the indicator)

Answer: (A)

Verified step by step guidance

1. Understand the context of a volumetric titration: it is an analytical technique used to determine the concentration or amount of a specific substance in a sample by reacting it with a solution of known concentration.
2. Identify the key components involved in a titration: the analyte, the titrant, the solvent (diluent), and the indicator.
3. Define the analyte as the species present in the sample whose concentration or amount you want to find out through the titration process.
4. Recognize that the titrant is the standard solution of known concentration added from the buret to react with the analyte.
5. Note that the solvent or diluent is used to dissolve the sample and reagents, and the indicator is a compound added to signal the end point by a color change, but neither is the analyte.
