When working with gas mixtures we often use the approximation that the gas mixture is ideal. However,
when studying condensed phases, the simple solution model is often inappropriate.
1. Dene what is meant by ideal behavior for a gas mixture or a condensed phase solution in terms of
the chemical potential of the components.
2. Explain how you might incorporate non-ideal behavior to describe a gas mixture. In your answer, state
what experimental data would be required and how it would be used to modify the chemical potential.
3. Explain how you might incorporate non-ideal behavior to describe condensed phase solutions. In your
answer state what experimental data you would require and how it would be used to modify the
chemical potential.
4. Is the chemical potential of an ion in solution a physically meaningful quantity? Explain your answer.
If you answer yes, explain how it could be determined experimentally. If you answer no, explain how
we are able to tabulate values of
fG for ions.
