Study Notes
Electrolysis and Polarography
- The technique concerned with the study of voltage-current relationships during electrolysis in a cell is known as polarography.
- The potential at which a substance begins to oxidize or reduce is called the half-wave potential.
- The small current that exists even in the absence of the analyte is referred to as the residual current.
- The region in the polarogram where the current becomes independent of the applied potential and the working electrode is completely polarized is called the limiting current region.
- The current required for charging the electrical double layer at the surface of a mercury electrode is called the capacitive current.
