As it is discussed in the volumetric glassware and selection of sample size and titrant volume sections, using 50 mL burettes and about 80-90% of their volume guarantees the smallest possible relative error of titration (it doesn't guarantee accuracy of the determination).

We can also minimalize errors carefully selecting volumes of pipettes and burettes used. If for some reason calibration can't be done, we can minimalize errors using A class volumetric glass.

These can be adjusted for by careful calibration of the glassware. Then, there are errors that can be connected with volumetric glass accuracy. While this is also intrinsic characteristic of the method, it can be adjusted for by blind trials. In some cases excess of the titrant must be used as it is titrant color that signals end point. Reasons of this difference are discussed in details in the end point detection and acid-base titration end point detection sections. There are several types of errors that can make titration result differ from the reality.įirst, there is an intrinsic error of the method - end point is not identical with equivalence point and color changes of indicators are not instant.
