1. What is the observable evidence of a precipitation reaction?
Formation of a gas
Change in temperature
Formation of an insoluble solid
Change in color (without solid formation)
2. Which of the following compounds is generally soluble in water?
AgCl
PbSO₄
KNO₃
BaSO₄
3. A precipitate is an solid formed during a chemical reaction in a solution.
4. The general term for a reaction that produces an insoluble solid when two soluble ionic compounds are mixed is a reaction.
5. According to solubility rules, most compounds containing ions (e.g., Na⁺, K⁺) are soluble.
6. All nitrates (NO₃⁻) are soluble.
True
False
7. If a reaction produces water as a product, it is always a precipitation reaction.
True
False
8. Describe how you would use solubility rules to predict if a precipitate will form when two ionic solutions are mixed.
9. For the following reaction, predict the products and identify any precipitate formed. Write the balanced molecular equation.
