What is an important property of a good titrant?

A good titrant is essential for accurate and reliable titration results, and one of the most important properties is that it should have a known and stable concentration. This stability ensures that the amount of titrant being added during the titration is consistent and accurately reflects the concentration of the solution being analyzed. If the concentration of the titrant is not known or varies significantly, the calculations to determine the concentration of the analyte would be unreliable, leading to erroneous results.

Having a known concentration allows for precise stoichiometric calculations, which are critical in determining the equivalence point of the titration. Furthermore, a stable concentration over time guarantees that the titrant to be used remains effective and can be reliably utilized in experiments conducted either immediately or after some time has passed. This property is fundamental in achieving reproducibility in laboratory results.
