Reaction Products Worksheet - Key For each of the following reactions, determine what the products of each reaction will be. When you have predicted the products, balance the equation and use a table of solubility products to determine which of the products (if any) will precipitate. Remember in order for a chemical change to occur both reactants must be aqueous and one of the products must be leave the solution (as a gas, a precipitate, or form a molecular compound such as H2O). Check to see that both of the starting reactants are aqueous (soluble in water) or else the reaction will not occur. 1) 1 Ca(OH)2 + 2 HF → 2 H2O + CaF2 (CaF2 precipitates) 2) 1 Pb(NO3)2 + 1 K2CrO4 → 2 KNO3 + PbCrO4 (PbCrO4 precipitates) 3) 2 NaC2H3O2 + 1 H2SO4 → Na2SO4 + 2 CH3COOH (no precipitate, thus no rxn) 4) 3 Cu(OH)2 + 2 H3PO4 → 6 H2O + Cu3(PO4)2 copper (II) phosphate precipitates 5) 2 AgNO3 + 1 Na2CO3 → Ag2CO3 + 2 NaNO3 (Ag2CO3 precipitates) 6) Pb(OH)2 + Hg2S → no reaction; neither reagent is soluble in water
