Pupil performing titration. Schoolgirl dripping measured volumes of a titrant (in this case an iron II salt) from a burette (down centre) into a reagent in a conical flask. Titration is a method of volumetric analysis, which allows the concentration of the titrant to be calculated if the concentration of the other reagent is known.
