Laboratory acid-base titrations are essential analytical techniques widely used for quantifying the concentration of unknown acid or base solutions. These titrations involve carefully adding a standardized solution of known concentration (titrant) to an analyte solution of unknown concentration until the reaction between the acid and base is complete. The progress of the titration is monitored using an indicator that changes color at a specific pH value known as the equivalence point. This point indicates that the moles of acid and base added are stoichiometrically equivalent, allowing for precise determination of the unknown concentration.
