Caption: MODEL RELEASED. Titration experiment. Student taking a volume reading from a burette during an acid-base titration experiment. This involves addition of an acid to a base, or vice-versa, with the burette used to measure the volume of a known concentration added to a known volume in a conical flask. Colour changes in the indicator used show when the mixture has reached a neutral pH. This then allows known and measured volumes and the known concentration to be used in a calculation of the unknown concentration in the conical flask. The indicator used depends on the acid and base used.
