Potentiometry and Electrochemical Cell Potential

Description

Potentiometry measures the potential difference between two electrodes in an electrochemical cell. It does this without drawing significant current, so the solution’s composition is not altered. The method uses an indicator electrode, which exchanges electrons with the analyte solution, and a reference electrode, which keeps...

Transcript

Potentiometry measures the potential difference between two electrodes without drawing any significant current that would change the solution's composition through the electrochemical cell.

The cell uses an indicator electrode that exchanges electrons with the analyte solution and either a reference electrode in the same solution or anoth...
