We’re being asked to determine which of the given reactions are the precipitation and non-precipitation reactions. Recall that in a precipitation reaction, a solid is formed as a product (precipitate).

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+)
