Topic: Redox and Electrochemistry
The student should be able to:
- Determine the oxidation state of an element in a given
compound or ionic species.
- Define and recognize examples of oxidation and reduction.
- Balance redox equations in either acidic or basic media using
the ion-electron (half-equation) method.
- Identify the oxidizing agent and the reducing agent in a given
redox reaction.
- Determine the equivalent weight of an oxidizing agent or
reducing agent given a balanced redox equation.
- Determine the normality of a solution of oxidizing agent or
reducing agent given its molarity and a balanced redox
equation.
- Solve titration problems related to redox reactions given
volume and molarity/normality data.
- Differentiate between a galvanic (voltaic) cell and an
electrolytic cell.
- Define and recognize examples of electrolysis.
- Recognize the anode and the cathode of an electrochemical cell
based on
- the chemical reaction occurring at each.
- Write the conventional notation for a galvanic cell given its
components.
- Draw a (crude) diagram of a galvanic cell given its components
or its conventional notation.
- Define standard reduction potentials.
- Determine the cell potential for a spontaneous redox reaction
given its standard reduction potentials for the half-cell
reactions.
- Predict the feasibility of redox reactions given a table of
standard reduction potentials for the half-cell reactions.
- Given a list of standard reduction potentials for various
half-cell reactions, predict which species would be the most
(least) powerful oxidizing agent and which would be the most
(least) powerful reducing agent.
- Determine the equilibrium constant for a given galvanic cell
from its standard cell potential.
- Calculate the cell potential of a galvanic cell at other than
standard conditions using the Nernst equation.
- Relate the magnitude of the standard cell potential to the
magnitude of the equilibrium constant and to the standard free
energy change for the redox reaction.
- For an electrolytic cell, use Faraday's law to calculate the
mass of a chemical species that is consumed/produced in a redox
reaction.
