Secondary Reference Electrode Definition. The hydrogen electrode is the primary reference electrode. Glass electrode cannot be used as secondary reference electrode.
This is also the case in an electrolytic cell. A reference electrode has a known electrode potential and is stable. When the cell is being discharged it behaves like a primary cell with the anode as the negative and the cathode as the positive electrode.
This allows the potential of the other half cell to be determined.
A standard hydrogen electrode is used as a reference electrode to measure the electrode potential. A calomel electrode b silver silver chloride electrode c mercury mercury sulphate electrode d glass electrode answer. When the cell is being discharged it behaves like a primary cell with the anode as the negative and the cathode as the positive electrode. Which of the following cannot be used as secondary reference electrode.
