(titrimetry, volumetric analysis)
(analyzing a chemical solution by color change)

Titration (or titrimetry or volumetric analysis) is the process of adding one solution to another until it changes color, to analyze the contents of the second solution. One takes a given volume of some solution that has an unknown amount of some compound (termed the analyte), and adds small, known amounts of a compound (a titrant) that causes a color-change when in the presence of the analyte at or above a particular volume ratio. When the color of the sample changes, and the amount of the titrant that brought on this change is noted, the analyte's percent of the original solution can be calculated.
