Experiment 2: Synthesis of Potassium Tris(oxalato)Ferrate(III) Trihydrate 2 – 5 Name: _____________________________ Date: _________________________________ Lab Instructor: ______________________ Lab Section: ___________________________ EXPERIMENT 2 Synthesis of Potassium Tris(oxalato)ferrate(III) Trihydrate Pre-laboratory Questions: 1. A student carried out the synthesis described in this experiment. In the first step of the synthesis, the student combined 4.888 g of Fe(NH 4 ) 2 (SO 4 ) 2 ·6H 2 O with 25.0 mL of 1.0 M H 2 C 2 O 4 . In the second step of the synthesis, the student added 20.0 mL of saturated K 2 C 2 O 4 , 20.0 mL of 3% H 2 O 2 , and 8.0 mL of 1.0 M H 2 C 2 O 4 to the solid FeC 2 O 4 ·2H 2 O produced in the first step.
