redoxtitrieringar

Redoxtitreringar, also known as oxidation-reduction titrations, are a type of chemical analysis used to determine the concentration of an analyte. This method relies on a redox reaction between the analyte and a titrant of known concentration. A redox reaction involves the transfer of electrons between chemical species. One species is oxidized, losing electrons, while another is reduced, gaining electrons. In a redoxtitrering, the titrant is a strong oxidizing or reducing agent that reacts quantitatively with the analyte. The progress of the titration is monitored until the equivalence point is reached, where the moles of titrant added are stoichiometrically equivalent to the moles of analyte present. This equivalence point is typically detected using an indicator that changes color when the redox potential of the solution shifts, or by using an electrochemical method like potentiometry. Common examples of redoxtitreringar include iodometry, permanganometry, and dichromatometry, each employing specific oxidizing or reducing agents. These titrations are widely used in various fields, including environmental monitoring, pharmaceutical analysis, and industrial quality control.
