Review sheet for Exam 2 Chemistry 103 Spring 2010 Chapter 16 topics 1. Buffer solutions, including creating buffers, buffer capacity, buffer reactions, and pH calculations. 2. Titrations, including equivalence point vs. endpoint, buffer region, and pH calculations. 3. Solubility equilibrium, including saturated vs. unsaturated (Q vs. K), K sp , solubility calculations, and Le Chatelier’s principle (e.g., common ion effect). Chapter 17 topics 1. Entropy, including the concept of dispersal of energy, absolute entropy and the third law of thermodynamics, second law of thermodynamics, and qualitative predictions and quantitative calculations for changes in entropy. 2. Gibbs free energy, including its relationship to entropy of the universe, and as a
