Area of Electrode

Go Area of Electrode = (Cathodic Current/(2.69*(10^8)*Number of electrons given CI*Concentration given CI*(Diffusion Constant^0.5)*(Sweep Rate^0.5)))^(2/3)

Applied Potential

Go Applied Potential in Potentiometry = Cell Potential in Potentiometry+(Current in Potentiometry*Resistance in Potentiometry)

Anodic Potential

Go Anodic Potential = Cathodic Potential+(57/Moles of Electron)

Anodic Potential given half potential

Go Anodic Potential = (Half Potential/0.5)-Cathodic Potential

Indicator EMF Formula

Indicator EMF = Reference EMF-Junction EMF+Cell Potential in Potentiometry
Ei = Er-Ej+E_cell

What is the basic principle of potentiometry?

The potential difference between the two electrodes used forms the basis of the potentiometry principle. The addition of a titrant leads to a change in the ionic concentration, causing changes in the potential difference. The indicator electrode measures this potential difference.

How to Calculate Indicator EMF?
