We will refer to the solubility rules in order to determine which compounds are soluble or insoluble.
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
▪ 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:
Determine if each compound shown is soluble or insoluble.
AgNO3
NaCl
Zn(OH)2
Hg2I2
KNO3
BaCl2
KBr
FeCl3
BaSO4
