Here are some study ideas for Exam 4, over Chapter 13 in IMT and Chapter 19 in Moore, Stanitski, and Jurs.

Click here to go to the IMT Concept Index for Chapter 13, which has additional notes
on this topic as well as several types of exam questions.

Be sure to look over Experiments 7 and 8 and ask yourself,
"What is a 20-point question that could be asked about this experiment?"

a. You should be able to determine the oxidation state of a chemical species given its molecular formula.
b. You should be able to write the two half-reactions given a redox equation, identify them as oxidation or reduction, use them to balance the overall equation in acid or base, and determine the number of electrons transferred in the overall balanced chemical equation.
c. You should be able to design an electrochemical cell based on redox reaction, identify the reactions at the anode and the cathode, and indicate the direction of movement of cations, anions, and electrons.
d. You should be able to use a table of standard reduction potentials to predict the voltage of an electrochemical cell under standard conditions and to predict reactivity (what reacts with what).
e. You should be able to use a table of standard reduction potentials and the Nernst equation to predict the voltage of an electrochemical cell under nonstandard conditions.
f. You should be able to discuss the relationship between free energy and electrical work and to rationalize the signs (+/-) of these quantities.
g. You should be able to relate the charge passed through an electrical circuit (I*t) to the amounts of reactants and products involved in the chemical reaction occurring in a battery or fuel cell.
h. You should be able to determine DELTA_Go associated with the equation for a redox reaction based on information given in a table of standard reduction potentials.
i. You should be able to determine equilibrium constants (at 25 oC, at least) based on information given in a table of standard reduction potentials.
j. You should be able to discuss the effect of temperature on cell voltage as an extension of what you know about the effect of temperature on DELTA_G.
