In a titration, what is the difference between the titrant and the analyte?
AThe titrant is the solid and the analyte the liquid
BThe titrant is of known concentration, the analyte unknown
CThe titrant is always an acid and the analyte a base
DThe titrant is the dye and the analyte the solvent used
Answer & Solution
Correct answer: B. The titrant is of known concentration, the analyte unknown
1. The titrant is the solution whose concentration is already known.
2. It is added in small portions to the sample from a buret.
3. The analyte is the substance in the sample whose concentration is being measured.
4. The two react in known stoichiometry, so the titrant volume used gives the analyte amount.
5. Either one may be the acid or the base, so their chemical role is not the distinction.
