What is electrode potential of a metal?
The tendency of an electrode to lose or gain electrons when it is in contact with its own ions in solution is called electrode potential.
What are electrode potential values?
Standard electrode potential is a measurement of the potential for equilibrium. There is a potential difference between the electrode and the electrolyte called the potential of the electrode.
Which metal has highest electrochemical potential?
So in terms of standard oxidation potential Zinc will have the highest oxidation potential i.e, 0.762 volts. Therefore, zinc is the strongest reducing agent.
What is the potential of a metal?
Electrode Potentials A metal in a steady state with a solution containing ions of the metal has a potential difference, the contact potential or electrode potential, between it and the solution. The contact potential cannot be measured with a single reversible electrode, and the circuit shown in the diagram is used.
