For this problem, we need the solubility rules:
• Soluble Ionic Compounds:
• Group 1A ions (Li+, Na+, K+, etc.) and Ammonium ion (NH4+) are soluble
• Nitrates (NO3–), Acetates (CH3COO– or C2H3O2–), and most Perchlorates (ClO4–) are soluble
• Halides (Cl–, Br–, and I–) are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+
• Sulfates (SO42–) are soluble except those of Ca2+, Sr2+, Ba2+, Ag+, and Pb2+
• Insoluble Ionic Compounds:
• Hydroxides (OH–) and Sulfides (S2–) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.), ammonium ion (NH4+), Ca2+, Sr2+, and Ba2+
• Carbonates (CO32–) and Phosphates (PO43–) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+)
