General Chemistry I (CHEM 101) Ksp, Molar Solubility, and Selective Precipitation Practice Problems
University of Florida
General Chemistry I (CHEM 101) | Practice Problems

Overview
A finals-focused practice set on Ksp calculations, molar solubility, and selective precipitation decision-making.

Key topics
•writing Ksp expressions
•solving for molar solubility
•common ion effect
•selective precipitation ordering

Suggested study tasks
•compute molar solubility from Ksp for a salt
•predict solubility change after adding a common ion
•choose which salt precipitates first given ion concentrations

Common pitfalls
•using incorrect stoichiometric exponents in Ksp
•mixing up s with concentration for multi-ion salts
•skipping a quick reasonableness check
