We are asked to identify the precipitate formed when solutions of ammonium sulfate and calcium acetate are mixed. 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 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+
Predict whether a precipitation reaction will occur when aqueous solutions of ammonium sulfate and calcium acetate are mixed. Write the net ionic equation.
