Question

Potentiometric acid base titration using quinhydrone electrode

Answer 1

Potentiometric titrations are experiments used for studying redox titrations. In a chemical experiment, the quinhydrone electrode is a kind of a redox electrode which is used for measuring the pH or the hydrogen ion concentration of a solution.

Answer 2

Quinhydrone electrode and glass electrodes are used as indicator electrode. In acid-base titration hydrogen ion is the ion being titrated, its concentration changes during the titration. Hence, in acid-base titration indicator electrode should be an electrode reversible to hydrogen ion.
