The image above represents electrode potential. Three essential parameters are needed to calculate electrode potential: standard electrode potential (Eo), number of electrons (n), and molar activity (cion**).**

**The formula for calculating electrode potential:**

E = E_{o} – ^{0.059}/_{n}In(C_{ion})

Where:

E = Electrode Potential | Nernst Equation

E_{o} = Standard Electrode Potential

n = Number of Electrons

C_{ion} = Molar Activity

Let’s solve an example;

Find the electrode potential when the standard electrode potential is 14, the number of electrons is 10 and the molar activity is 12.

This implies that;

E_{o} = Standard Electrode Potential = 14

n = Number of Electrons = 10

C_{ion} = Molar Activity = 12

E = E_{o} – ^{0.059}/_{n}In(C_{ion})

E = 14 – ^{0.059}/_{10}In(12)

So, E = 14 – (0.0059)(2.48)

E = 14 – 0.0146

E = 13.98

Therefore, theÂ **electrode potentialÂ **isÂ **13.98 V.**
