Caption: Titration experiment. Student using a piece of white card to demonstrate how to take an accurate reading when viewing the liquid level in a burette. Acid-base titration 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.
