Chemistry: Solution Equilibria

Problem Sets || Overview of Solution Equilibria

We are planning to make 13 ready-to-use problem sets on the topic of solution equilibria. These problem sets will focus on the analysis of situations in which partially soluble salts, weak acids, and weak bases are dissolved in water. The use of an ICE table and dissociation equation to solve K_sp, K_a, and K_b problems will be emphasized. Problems will range in difficulty; most will require moderate to sophisticated algbraic manipulations.
