In our everyday lives, human beings deal with very few pure substances. A solution is a homogeneous mixture, while a colloid is a heterogeneous mixture. Important new terminology regarding solutions is presented in this chapter, the final chapter covered in CHEM 200.
Topics covered include intermolecular forces in solution and gaso and solid solutions.
Polarity is an important concept in the mechanisms of antibiotics as well. 12.2 Energy Changes in the Solution Process Sub-sections within 12.2 include discussion of heats of solution and hydration, as well as the importance of entropy in the solution process. 12.3 Solubility as an Equilibrium Process Important terms in Section 12.3 include saturated, unsaturated, and super-saturated. Topics covered in 12.3 include the effects of temperature and pressure on solubility. 12.4 Quantitative Ways of Expressing Concentration Molarity was introduced in Chapter 3 as a means for quantifying the concentrations of solutions.
