Read each question carefully and answer to the best of your ability. Refer to your knowledge of solubility rules for ionic compounds.
1. Which of the following compounds is generally soluble in water?
AgCl
PbSO4
NaNO3
BaCO3
2. According to solubility rules, most sulfates are soluble. Which of the following sulfates is an exception and therefore insoluble?
MgSO4
Al2(SO4)3
CaSO4
K2SO4
3. All compounds containing nitrate (NO3-) ions are in water.
4. Most chlorides (Cl-) are soluble, except for those containing Ag+, Pb2+, and .
5. Compounds containing Group 1 metal cations (e.g., Na+, K+) are always .
6. All carbonates (CO3^2-) are insoluble in water.
True
False
7. Sodium hydroxide (NaOH) is an insoluble compound.
True
False
8. Predict whether a precipitate will form when aqueous solutions of potassium iodide (KI) and lead(II) nitrate (Pb(NO3)2) are mixed. Explain your reasoning.
9. You have an unknown white solid. When added to water, it dissolves completely. When silver nitrate (AgNO3) solution is added to this solution, a white precipitate forms. Based on this observation, what could be a possible anion in the unknown white solid? Explain.
