EMF at Cell Junction Formula

LaTeX Go

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

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.
