titrations
Drop-by-drop determinations
Titrations are laboratory procedures for determining the concentration of a substance by gradually adding a reagent of known concentration until a chemical reaction reaches completion.
The endpoint is typically marked by a color change or other indicator.
The chemistry students performed titrations to find the acid concentration in their samples.
