Electrolysis
Redox Reactions
Studies on about the chemical reactions produced by electric energy.
_SLIDE_3_
Electrolysis: In some electrochemical cells non-spontaneous (reactant-favored) chemical reactions are forced to occur by the input of electrical energy.
☞ In order to occur this reaction, we should apply more higher than
a potential difference of spontaneous reaction.
Cf. Chemical cell
: electricity is generated by spontaneous chemical redox reaction.

Anode: The electrode at which oxidation occurs
Cathode: The electrode at which reduction occurs
Anode: Zn → Zn2+ + 2e-
Cathode: Cu2+ + 2e-→ Cu
Overall: Cu2+ + Zn →Cu + Zn2+
