ABSTRACT
Summary • Oxidation occurs at the anod
being oxidised lose their elec positively charged cations w towards the cathode.
4aqFe2sFe4 22
• Reduction occurs at the cath charged ions in solution take coming from the oxidation re neutral atoms. The remaining anions tend to move towards
2aqCusCu 2 2aqZnsZn 2 e2H2gH22
Ag2e22Ag2 H2e22H 2 sCue2Cu 2
e. Neutral atoms trons and become hich tend to move
e Oxidation occurs
ode. Positively up the electrons action and become negatively charged the anode
e e
when the oxidation number of an atom is increased (loss of electrons).
