The document describes the preparation and analysis of the complex potassium tris(oxalato)ferrate(III), K3[Fe(C2O4)3].3H2O. It involves a multi-step synthesis including precipitation, washing, and crystallization. Analysis includes titration with potassium permanganate to determine purity and percent yield. Additional experiments measure the complex's use as an actinometer to determine the rate of photon absorption. Results found the percent yield was 68% and percent purity was 99.69%, with potential sources of error discussed.
