We are asked to determine whether precipitation will occur when FeSO4 and Pb(NO3)2 are mixed.
Recall that precipitation is a type of double displacement reaction that forms an insoluble (s) product or a precipitate.
We will refer to the solubility rules in order to determine if an insoluble product is formed or not.
•Soluble Ionic Compounds:
▪Group 1A ions (Li+, Na+, K+, etc.) and Ammoniumion (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:
Will precipitation occur when the following solutions are mixed?
FeSO4 and Pb(NO3)2
