Predicting Precipitates with Solubility Rules
Learning Objective
I can use a Solubility chart to predict whether a precipitate will form in an aqueous solution.
Key Concepts
A solubility table helps determine if a compound is soluble (aqueous) or insoluble (solid).
Group 1 metals, ammonium, nitrate, and acetate are generally soluble with no exceptions.
Halogens are typically soluble, except when combined with silver, lead, or mercury, which makes them insoluble.
Practice Questions
This lesson includes 12 practice questions to reinforce learning.

1. According to the solubility rules, which of the following ions, when combined with silver (Ag+), would form an insoluble compound?
2. Using the solubility rules, predict whether barium sulfate (BaSO₄) is soluble or insoluble in water. Explain your reasoning.
3. Will a precipitate form when solutions of lead(II) nitrate (Pb(NO₃)₂) and potassium iodide (KI) are mixed? Explain using solubility rules.
