Pupil performing titration. Schoolgirl dripping measured volumes of an acid from a burette (down centre). The conical flask (lower centre) contains a measured volume of an alkali and an indicator, giving it a pink colour. As the acid and alkali mix they change the pH of the solution. When the acid and alkali neutralize, the indicator changes colour.
