Question

What are the potentiometric tatraion

Answer 1

Potentiometric titration is a titration method that determines the concentration of an analyte by measuring the electrical potential difference between two electrodes (an indicator electrode and a reference electrode) as a titrant is added. The equivalence point is detected by observing a significant change in potential.

Answer 2

Potentiometric titration is an analytical technique used to determine the concentration of a substance by measuring the potential difference (voltage) between two electrodes immersed in the solution as a titrant is added. One electrode is an indicator electrode sensitive to the concentration of the analyte or titrant, and the other is a reference electrode with a stable potential. The potential difference changes significantly at the equivalence point of the titration, which is detected by plotting the potential against the volume of titrant added.

Explanation: Potentiometric titration is a method where the potential difference between an indicator electrode and a reference electrode is measured as a function of the volume of titrant added. The indicator electrode's potential is dependent on the concentration of the analyte or titrant species. The reference electrode maintains a constant potential. The equivalence point is identified from the steep change in the measured potential, typically observed as the inflection point in the plot of potential versus titrant volume, or as a peak in the first derivative plot (dV/d volume) or a zero crossing in the second derivative plot (d²V/d volume²).
