Chapter 2 Electroanalytical Methods- Potentiometry Potentiometry Potential is measured under the conditions of no current flow The measured potential is proportional to the concentration of some component of the analyte The potential that develops in the electrochemical cell is the result of the free energy change that would occur if the chemical phenomena were to proceed until the equilibrium condition has been satisfied. Basic Principles ...
