Explanation

reference electrode refers to the electrode used for reference and comparison when measuring the potential of various electrodes. The measured electrode and the reference electrode with precisely known electrode potential value form a battery. The electrode potential of the measured electrode can be calculated by measuring the battery electromotive force value. The electrode reaction on the reference electrode must be a single reversible reaction with stable electrode potential and good reproducibility. Generally, the slightly soluble salt electrode is used as the reference electrode, and the hydrogen electrode is only an ideal but not easy to realize reference electrode.
