SäureBaseTitrierungen

SäureBaseTitrierungen, also known as acid-base titrations, are quantitative analytical methods used to determine the concentration of an unknown acid or base solution. This is achieved by reacting it with a solution of known concentration, called a titrant, until the reaction is complete. The key principle relies on the neutralization reaction between an acid and a base. During the titration, the titrant is gradually added to the analyte (the solution with unknown concentration) until the equivalence point is reached. At the equivalence point, the moles of acid and base have reacted stoichiometrically. To detect this point, an indicator is often used, a substance that changes color at a specific pH range. Alternatively, a pH meter can be employed to monitor the pH changes throughout the titration and precisely identify the equivalence point. The volume of titrant added to reach the equivalence point, along with the known concentration of the titrant and the volume of the analyte, allows for the calculation of the analyte's concentration using stoichiometric relationships. These titrations are fundamental in chemistry for determining unknown concentrations and are widely applied in various fields, including pharmaceuticals, environmental monitoring, and food analysis.
