Inserir no projetoP3061640Curvas de titulação e capacidade tamponante com Cobra3


pH values can be measured with the aid of electrochemical measurements and proton-sensitive electrodes (e.g. glass electrodes). By combining a glass electrode with a reference electrode in one housing, a single-rod glass electrode, which is appropriate for acid-base titrations, is created. The titration curves allow an exact determination of the equivalence point in titrations of strong and weak acids and bases.


  • Determine the titration curves of different neutralisation reactions.
  • Determine the titration curve of an ampholyte (glycine).
  • Determine the buffering capacity of various aqueous acetic acid/sodium acetate mixtures at different total concentrations.
