Which term describes the solution that is being added and its volume is measured during titration?

• A. Endpoint
• B. Equivalence point
• C. Primary standard
• D. Titrant

Answer: (B)

In a titration, the solution you are adding from the burette is the titrant, and you measure how much of it you have added—the titrant’s volume. The equivalence point is the moment when the amount of titrant exactly reacts with the analyte, a concept about the reaction’s balance rather than the substance you’re adding. The endpoint is the observable signal (like a color change) indicating you’ve reached near that point. A primary standard is a pure substance used to calibrate the titrant, not the added solution itself. So the term that describes the solution being added and its volume is titrant.
