Electrode Potentials (OCR A-Level Chemistry A): Flashcards

Device converting chemical energy to electrical energy

Contains all species in one half of a redox equation

$E°$

298 K, 100 kPa, 1 mol dm$^{-3}$

0 V

Allows ion flow between solutions, completes circuit

Greater tendency to gain electrons (undergo reduction)

Greater tendency to lose electrons (undergo oxidation)

$E°_{cell} = E°(positive) - E°(negative)$

Positive electrode (cathode)
