Use the sоlubility tаble tо write the cоmplete ionic equаtion for the reаction if any precipitate is formed that occurs when aqueous solutions of lithium chloride (LiCl) and silver nitrate (AgNO3) are mixed. Table 1. Guidelines for predicting the solubility of ionic compounds in water Rule Soluble Insoluble 1 Most salts that contain the alkali metal (Li+, Na+, K+, Rb+, Cs+) and ammonium (NH4+) 2 Most salts that contain the nitrate (NO3-) anion 3 Most salts of anions derived from monocarboxylic acids (such as CH3CO2-) Silver acetate and salts of long-chain carboxylates 4 Most chloride, bromide, and iodide salts Salts of metal ions in the lower right side of the periodic table, such as Cu+, Ag+, Pb2+, and Hg22+ 5 Sulfate (SO42-) salts that contain +1 cations, Mg2+, and dipositive transition metal cations (such as Ni2+) Cations derived from main group elements with ≥ +2 charge, such as the metals of Groups 2 (except Mg2+), 3, and 13 and Pb2+ 6 6 Most ionic compounds that contain the hydroxide(OH-) and sulfide(S2-) anions and alkali metal (Group 1) and alkaline earth (Group 2) and ammonium cations Be(OH)2 and Mg(OH)2 Most other cations 7 Carbonate (CO32-) and phosphate (PO43-) salts that contain alkali metal or ammonium cations Most other metal cations
