FREE Expert Solution

Refer to solubility rules for ionic salts:

• Insoluble Ionic Compounds:

▪ Cl-, Br-, and I- paired with Ag+, Pb2+, Cu+, Hg22+

▪ Sulfates (SO42-) of Ca2+, Sr2+, Ba2+, Ag+, and Pb2+
Hydroxides (OH-) and Sulfides (S2-) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+) and Ca2+, Sr2+, Ba2+
 ▪ Carbonates (CO32-) and Phosphates (PO43-) are insoluble except when with Group 1A ions (Li+, Na+, K+, etc.) and ammonium ion (NH4+)
