The solution of known concentration in a titration is called the:

• A. trand
• B. titration solution
• C. titrant
• D. solvent

Answer: (C)

In a titration, the solution of known concentration is called the titrant. This reagent is added from a buret into the sample (the analyte) until the reaction is complete, allowing you to determine the unknown concentration from the amount of titrant used. Knowing the titrant’s concentration makes the calculation possible through stoichiometry, because you can relate the moles of titrant to the moles of analyte at the point of neutralization or equivalence. The other terms aren’t as precise: a misspelled or nonstandard term isn’t used, a general “titration solution” could refer to anything involved in the process, and the solvent is just the liquid that dissolves things, not the reactive reagent with a known concentration.
