{{further|Titration}}
Titration involves the gradual addition of a measurable reactant to an exact volume of a solution being analyzed until some equivalence point is reached. Titration is a family of techniques used to determine the concentration of an analyte.<ref name=":0">{{Cite book |author=Douglas A.

Most familiar to those who have taken chemistry during secondary education is the acid-base titration involving a color-changing indicator, such as [[phenolphthalein]].  There are many other types of titrations, for example, potentiometric titrations or precipitation titrations. Chemists might also create titration curves in order by systematically testing the pH every drop in order to understand different properties of the titrant.
