Quiz 6 material

Quiz 6:  Chapter 20 and Ch 23 (23.1-23.2)

Sections 20.1-20.5:

Understand oxidation states (oxidation numbers), redox reactions,
what is oxidized and reduced and what are oxidizing and reducing
agents (oxidant and reductant).

Be able to balance redox reactions using the half-rxn method.

Understand voltaic cells.  Remember, oxidation occurs at the
anode and reduction at the cathode.  Understand the shorthand
notation as given in lecture and the notes (and homework
exercise 20.99 in 12th ed., 20.95 in the 11th ed. and 20.93
in the 10th ed.).

Understand cell potentials and standard cell potentials and
how the two are related.  Understand how to calculate them
from reduction potentials.  Understand how standard reduction
potentials relate to the strengths of oxidizing and reducing
agents.  You need to know what is meant by standard conditions
(1 M for conc of things in soln and 1 atm partial pressures
for gases).

Understand how E and delta(G) are related and how E^o and
delta(G^o) and the equilibrium constant are related and that
a negative delta(G^o) and positive E^o indicate a spontaneous
rxn and a K > 1.

Section 20.6: Nernst Eqn. You should be able to use this eqn.
to calculate the E for a cell under nonstandard conditions.

Sections 20.7 & 20.8:  Batteries and fuel cells and corrosion.
Understand batteries in general, you don't need to memorize
specific batteries.

Section 20.9: Electrolysis, quantitative aspects of electrolysis
(stoichiometry).  What are the differences between voltaic and
electrolytic cells.

You should be able do to homework problems 20.1-20.119

For those of you using the 12th edition the quiz covers sections
20.1-20.9 and homework problems 20.1-20.120

For those of you using the 11th edition the quiz covers sections
20.1-20.9 and homework problems 20.1-20.121

For those of you using the 10th edition the quiz covers sections
20.1-20.9 and homework problems 20.1-20.119

Review section 4.4 (Redox Reactions).  It would also be a good idea to
do homework problems 4.9, 4.45-4.52 (4.9, 4.45-4.52 in the 11th edition
and 4.45-4.51 in 10th edition).  Also, see the following worksheet for
additional practice on oxidation numbers.

Chapter 23 (23.1-23.2) - for the 12th and 13th editions.

For the 10th and 11th ed. Chapter 23 (23.7) & Chapter 24 (24.1)

Transition metals, properties of transition metals, lanthanide contraction,
electron configurations and oxidation states (electrons come out of the s
orbitals first), magnetism (understand the different types).

Transition-metal complexes (ligands, complex ions, coordination cmpds),
coordination number, coordination sphere, metal-ligand bonding (Lewis
acid-base rxns), be able to determine oxidation number and coord. number of
the metal in a complex or coord. cmpd., geometries (often depend on the
ligand - ligands which carry substantial negative charge reduce the the 
coord.
number, i.e. # atoms directly bonded to metal atom)

You should be able do to homework problems 23.1, 23.3, 23.11-23.26,
23.65-23.69

For those of you using the 12th edition the quiz covers sections 
23.1-23.2 and
homework problems 23.1-23.3, 23.11-23.26, 23.65-23.69
