### Step-by-Step Solution 1. **Understanding Electrode Potential**: In electrochemistry, an electrode potential is the voltage developed by an electrode in an electrochemical cell. Each electrode can either undergo oxidation or reduction, but not both simultaneously. 2. **Half-Cells Concept**: An electrochemical cell consists of two half-cells: one for oxidation (anode) and one for reduction (cathode). The oxidation half-cell involves the loss of electrons, while the reduction half-cell involves the gain of electrons. 3. **Simultaneity of Reactions**: Oxidation and reduction reactions cannot occur at the same electrode at the same time. Therefore, to measure the potential of a single electrode, you would need to know how it behaves in relation to another electrode. ...

What are reference electrodes ? Which reference electrode used in measuring electrode potential of other electrodes ?

The potential associated. with each electrode is known as electrode potential. If the concentration of each species taking part in the electrode reaction is unity (if any gås appears in the electrode reaction, it is confined to 1 atmospheric pressure) and further the reaction is carried out at 298 K, then the potential of each electrode is said to be the standard electrode potential. By convention, the standard electrode potential of hydrogen electrode is 0:0 volt. The electrode potential value for each electrode process is a measure, of relative tendency of the active species in the process to remain in the oxidized / reduced form. A negative E^@ means that the redox couple is a stronger reducing agent than the H^(+)//H_2 couple. A positive E mears that the redox couple is a weaker reducing agent than. the H^(+)//H couple.
