Oxidation-reduction reactions, electrochemistry, electrolysis and corrosion
Main lesson
Standard cell voltage
Use this for “What voltage does a zinc–copper cell give?”: E°cell from the two metals’ reduction potentials.
Oxidation numbers: the atom to find
Use this for “What is the oxidation number of S in H₂SO₄?” or in SO₄²⁻.
Oxidized, reduced or neither?
Use this for “In Zn + Cu²⁺ → Zn²⁺ + Cu, which substance is oxidized?”
Galvanic or electrolytic cell?
Use this for “How is an electrolytic cell different from a battery?”
