MODEL RELEASED. Pupil performing titration. Schoolgirl dripping measured volumes of an acid from a burette (down centre). The conical flask (bottom centre) contains a measured volume of an alkali and the indicator methyl orange. As the acid & alkali mix they change the pH of the solution, resulting in a change in the indicator's colour. This reaction has gone beyond its end- point, resulting in an excess of acid in the conical flask. This has caused the methyl orange to change colour to pink.
