Precipitation Titration​

This is a method for titrimetric quantification based on the formation or disappearance of precipitates. Reagents that stoichiometrically react with the test article to form a sparingly soluble precipitate are used as titrants. Lower solubility of the formed precipitate enables more precise titration of solutions, even dilute ones. Examples of precipitation titration include argentometric titration, ferrocyanide titration, and thiocyanate titration. It is used particularly often as a quantification method for argentometric halides, cyanides, thiocyanates, sulfides, and other anions, as well as organic substances.​
