of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using
