Redox and electrode potentials Flashcards
1
Q
Which species is oxidised in an electrode? Does it gain or lose electrons?
A
The species with the lower electrode potential. It loses electrons.
2
Q
Which species is reduced in an electrode?
A
The species with the higher electrode potential. It gains electrons.
3
Q
