Experiment 2: Synthesis of Potassium Tris(oxalato)Ferrate(III) Trihydrate 2 – 2 The theoretical yield is the calculated maximum amount of product that might be obtained under ideal conditions from the reactants. In an experiment, the theoretical yield is seldom, if ever, reached. In this experiment, the theoretical yield is the maximum number of grams of product [K 3 Fe(C 2 O 4 ) 3 ·3H 2 O] that might be obtained from the specified amounts of reactants. To determine the percent yield, it is necessary to calculate the moles of each reactant and then find the limiting reagent. The limiting reagent determines the theoretical yield of potassium tris(oxalato)ferrate(III) trihydrate. Procedure: Week 1 Measure and record the mass of a 200 mL beaker. Add approximately 5 g of ferrous ammonium sulfate hexahydrate [Fe(NH 4 ) 2 (SO 4 ) 2 ·6H 2 O] to the beaker. Measure and record this combined mass. Determine the mass of Fe(NH 4 ) 2 (SO 4 ) 2 ·6H 2 O in the beaker by subtraction. Next, dissolve
