Study Guide Overview
This study guide covers the common ion effect on solubility equilibria. It explains how adding a common ion decreases solubility, using Le Chatelier's Principle. It includes practice problems involving Ksp calculations, ICE tables, and molar solubility with and without common ions. The guide also emphasizes the importance of this topic for the AP exam.
