We are asked to determine if a precipitate will form when two salts are mixed together. We will refer to the solubility rules in order to determine if an insoluble product (precipitate) is formed or not.
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:
Will precipitation occur when the following solutions are mixed?
NaNO3 and NiSO4
