Question

Difference between polarized and non polarized electrode

Answer 1

In electrochemistry, an ideal polarized electrode is contrasted with non-polarized eleteode(ideal) .

1) ideal polarized electrode has no faradic current (produced by oxidation or reduction) where as non-ideal polarized electrode has faradic current.

2) Polarized electrode-electrolyte interface acts like a capacitor.

3) Non-polarized electrode-electrolyte interface acts like a resistor.

Example of Non-polarized electrode is silver/silver chloride and polarized electrode example is platinum electrode.
