Lecture Summary, 14 January 2014
composition measurements: We discussed the most
commonly used solution composition measurements such as
concentration, mass percent, and mole fraction. While it is
important to be able to calculate accurately the solution
composition using any of these definitions, it is more important to
understand why a particular definition is more useful for a
particular solution or problem, and to be able to move between
different definitions efficiently.
Why solutions form: We also discussed intermolecular forces between different molecules to rationalize why some molecules will mix to form solutions and others will not.
