What is standard electrode potential?

Question

Answer

In electrochemistry, Standard Electrode Potential is defined as the measure of the individual potential of reversible electrode at standard state with ions at an effective concentration of 1mol dm-3 at the pressure of 1 atm The basis for an electrochemical cell,

Answer

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. When unity is the concentrations of all the species involved in a semi-cell, the electrode potential is known as the standard electrode potential.

Answer

Standard electrode potential is the potential of an electrode when the thermodynamic activity of all reactants in the half-cell reaction is equal to 1 (they are in a standard state). In Nernst equation:

E=E∘+RT/zFlnaOx/aRed

E∘ is the standard electrode potential
