Choosing indicators for titrations

WebUnderstand the use of indicators to monitor pH titrations; In an acid–base titration, a buret is used to deliver measured volumes of an acid or a base solution of known concentration (the titrant) to a flask that contains a solution of a base or an acid, respectively, of unknown concentration (the unknown). If the concentration of the titrant ... WebThe titration is typically performed as an acid into base. Following the titration with a pH meter in real time generates a curve showing the equivalence point. If the approximate pH of the equivalence point is known, a colorimetric indicator can be used in the titration. Key Terms. buffer: A solution used to stabilize the pH (acidity) of a liquid.
